“Aqua Kitty-Milk Mine Defender is a cute little arcade shooter that is too good to pass up. The graphics are pretty, the music is awesome, and it felt appropriately difficult on its own merit rather than me fighting the system. I’ve got little but praise for this game and felt it worth the price.”

About This Game

Aqua Kitty is a fast paced retro styled submarine arcade shooter with optional 2 player local Co-op.
Blast through hordes of mechanical sea monsters in your kitty sub and defend the deep sea milk mining kittens!


Due to a sudden shortage of milk, cats around the world are forced to seek out new sources to get their fix.
You and your team of milk mining kittens have overcome a fear of water to drill down under the ocean seabed and begin extracting vast reserves of what seems to be naturally forming full-fat milk.
Get ready for fast paced submarine action, defending the kittens from disruptive mechanical sea creatures.

Development history

Hello, here is a short history of this indie games' development which we hope will be of interest.
Aqua Kitty was made by a core team of two people with audio created by Electric Cafe and the game box art by artist David Hankin.
It began as a small modern-retro styled PC game, designed to run at a crisp 1280x720 it was created with a love of the 16bit gaming era and late 80s video arcade games.

There are 3 core versions of the game available of different hardware - PC, XBox360 and Sony PSM.

Sony version is the oldest and smallest version. A critically acclaimed launch title for PSM (Vita).

XBox version is the Sony version with extra added levels + enemies + refinements.

PC version is the most feature rich and improves on the XBox one with new Weapons + Gradius style Arcade mode + yet further refinements and extra details (with the Steam version being unique in having online leaderboards and achievements).

All the new things we have added to the Steam version will also be rolled back into the other PC versions unless Steam specific (ie Online leaderboards, achievements, trading cards are STEAM ONLY).

In the space year 20XX, the entire world's supply of milk appears to have "ran dry". This would suggest to me that sometime in the future all form of breasts will become either extinct or outlawed and force us to look elsewhere for our creamy goodness. As luck would have it for our kitty chums, though, "deep under the ocean, vast amounts of what appear to be naturally forming full fat milk were discovered". Don't ask me how the milk is now lying under the ocean. Perhaps all the world's mammaries will migrate to below the surface to escape danger or persecution in the future? Either way I guess it's only natural that boobs would eventually start heading downwards with the passage of time. But however they got there, the kitties are determined to get it out and launch an operation to mine it and send the milk gushing back forth into the world once more. But it's not a task without peril for our hungry kitties as they're attacked by unknown enemies who try to kidnap the underwater miners and keep all the lovely, delicious milk for themselves. "OH NOES!", cries the kitty captain. Oh noes, indeed. So out sets a brave pilot to shepherd the miners and destroy the threat, keeping his furry brethren in one piece and saving the world's milk(/boobs?) in the process...

If anybody says the story is dumb then you and me are gonna step outside and have words, alright?! Anyway, on with the review.

In Aqua Kitty - Milk Mine Defender, you'll pilot a small, one-man sub... one-cat sub? Whatever. You'll pilot a sub through stages that loop around on themselves and are no higher than the height of the screen, shooting waves of enemies until all have been wiped out while taking care not to lose all of your miners who walk the surface (as long as one is kept alive you're fine). Additional enemy types are gradually introduced as levels progress and power-ups are occasionally dished out to help your efforts. Its basic formula is simplicity itself, and in that comes so much of its addictive appeal and accessibility as the game sinks its claws into you and doesn't let go.

It isn't exactly laid out this way, but essentially there are three modes in the game. There's the standard style of play (available in easy and normal difficulties) where your progress is saved and failing a level means simply restarting it at any point from a map screen, while power-ups are temporary and don't carry on through stages. There's Arcade Mode, which sets you the challenge of making it through all 25 stages with one life, but with power-up drops being replaced by gems which can be used to purchase upgrades which do carry through stages but are also degraded with each hit you take. And then there's Infinite Espresso mode (also available in easy and normal) where you have to make it through as many waves as possible with one life and very limited power-ups, but at least with no miners to worry about.

There's a slight retro, SNES era style about the look of the game, complete with "chunky" sound effects and some outstanding music that never gets old and even manages to stay lodged in your head long after you've finished playing. Some people have commented about the game being too difficult. I don't really play many side scrolling shooters like this, and wouldn't consider myself especially gifted at them or anything, but I can't say I had all that much trouble with it. There were a few problem stages, sure, and achievement hunters beware, unless you have the twitchy reflexes of a coked-up cat with Tourette's on his fifth can of Red Bull then you're gonna have a ball-achingly hard time getting 100%. But to just complete the game and get most of the experience this has to offer, the rest of us mere mortals should do just fine.

I think it says a lot that even 30 or so hours into this game, no matter how many times I died I still more often than not had a smile on my face and rarely did I ever feel the game was cheap or unfair (maybe aside from the red, grabby b*astards that steal your miners. THEY SHOULDN'T BE ALLOWED TO FIRE! I swear I get nailed by their single, slow shots more than anything else). The hours easily flew by without me noticing and I found I had to stop myself from carrying on anymore trying to beat the harder challenges. If that's not a glowing recommendation for anything then I don't know what is. If I had any complaints it would be that sometimes your sub doesn't feel quite as sharp or responsive as you might like in some of the tighter spots. And while it's perfectly possible to play with a keyboard, I'd strongly advice using a controller. But otherwise, I loved almost everything about this game. Oh, except the fact they had a cat piloting a ship and didn't call him Commander Kitty... I'll never be able to forgive them for that.

I like the presentation and the music, and usually I don't mind difficulty in games, I grew up with games in the 80ies and 90ies and so I thought this game might be enjoyable for me.

In the long run, it was not. At level 10 I had to retry alot, it became tedious and annoying. And it stayed like that till the end... there is little incentive to go on, compared to the tedious retrying that is necessary for most of the later levels.

There is no story, no exploration in the levels or in the world map, no persistent ship powerups worthy of that name (looking at you, turbo cannon). Progression through gradual development of player skill is usually a motivation in many difficult or "oldschool" games, but here it is negligible, the mechanics are too shallow for that, and you constantly feel weak and the powerups are only temporary. Instead of "shoot'em up", this is an "avoid'em and shoot little peas from a safe distance", because in the later levels the enemies take alot of hits to kill.

Eventually I finished the game on easy but apart from the endboss and the achievements, there is NOTHING happening in the game that actually gives you motivation to keep trying.

Another annoyance is the radar: it does not center on your ship. That means when you want to get your bearing in a hectic situation, you will first have to search for your own ship's position on that small radar and that costs precious time when the main screen is full of enemies and their bullets. It forces you to keep your eyes on the radar and off the main screen for longer than necessary. You often loose health because of that, and it always feels frustrating.

All paws on deck! It's time to defend our milk!

I was fortunate enough to have this game gifted to me by a friend who had an extra copy. The title alone would have made me want it, but I also saw a livestreamer play some of it. I figured it would be a purrfect way to spend a few hours. Cue those few hours becoming many hours. It is a lot of fun, and not just because it has cute cats!

  • This was my first time playing an arcade shooter game. It is a good introduction to them. I enjoyed being in my submarine and shooting down robotic fish to save my milk-mining kitties from being stolen by evil jellyfish. It made me want to play more of this game and others like it.
  • The controls are great. They are smooth, responsive, and work exactly as they should. You can use a keyboard or controller. I have used the keyboard, and it worked perfectly fine, though some might prefer a controller.
  • While the game is difficult, it is fair. Every time I died, I blamed myself rather than some cheap move on the game's part. Certainly the waves of enemies are challenging, but all it takes is practice to get through them.
  • The power-up system is an interesting one. You can get three types of power-ups, all of which depend on where you shoot robotic fish capsules. If the fish is low, medium, or high up in the water, they give different power-ups. Since these fish appear at the same points in each level, not only can you plan when you get your power-ups, but also which power-ups you will receive. The lack of randomization adds to the strategy elements of Aqua Kitty - Milk Mine Defender.
  • A mini-map is in each level to help keep track of your miners and enemies. Thank goodness for that map, or it would be very hard to tell where you need to go to help your kitties. The cats will also let out pitiful mews if they are grabbed, which is a good warning for going over to save them.
  • There are 25 levels with three modes for playing them: easy, normal, and arcade. Easy and normal are different enough in terms of difficulty to make them worth having and experiencing. Arcade is insanely hard, because once you die there, you have to start all the way at the beginning. Good luck with that one!
  • One of the levels is an infinite mode. You continue playing until either you die or leave. The game keeps track of how many waves of enemies you kill, so this is a fun place to visit for testing your skills.
  • Retro graphics ahoy! They are good ones, and the game is pleasant to look at. Enjoy the numerous kitties spread throughout your playtime.
  • The music is great! There are not many tracks, but each one is a fine representation of how awesome chiptunes can be.
  • What little writing there is consists of cute and witty remarks.
  • There are 36 achievements of varying difficulty. Some are bound to be completed quickly, while others are only possible for the most experienced players. Achievement hunters beware, you won't be completing them that easily. But when you get those hard-as-heck achievements, you had better believe that it feels really, really good.
  • You are defending milk-mining kitties with a cat in a submarine. If you are still reading this review, why in the world have you not stopped to buy it?

  • There is barely any storyline or characterization. Since this is not the sort of game that really demands it, I don't care a whole lot.
  • Multiplayer exists for local co-op. I have not had anyone to try this with, but I did activate it once to see how it worked. It appears to be a solid feature that is fun for friends.
  • It does have trading cards. They consist of amusing kitty pictures from the game.

  • The difficulty spike. Holy carp the difficulty spike. Up until level thirteen, it is a game that is not incredibly easy, but simple enough. From level thirteen onward, the levels become brutal, and each one somehow manages to outdo the last. While some people might like the difficulty, it is such a jump from the easier levels that it is a very rude awakening.
  • Each stage has a number, but there are no names for the levels. This makes it difficult to remember which level is which. There is at least a grouping system of "locations" on the map. However, that only helps so much.
  • Arcade mode is insane to beat. While that may be great for hardcore gamers, it means completing the game fully is ridiculously difficult. More likely than not this game will never leave its "Beaten" status in my backloggery.

Overall experience:

I came for the kitties. I came back for the gameplay. I had no idea I was such a closet arcade shooter nerd, yet here we are. If you have any interest at all in difficult games of this genre, it is a near guarantee that Aqua Kitty - Milk Mine Defender will be a great game for your library.


8.5/10. It looks adorable, yet is hard enough to give almost anyone a run for their milk. So what are you waiting for? Go play this game right meow!

Despite the sweet looking cutie cats it isn't an easy game at all.
The gameplay is simple: kill everything, and save the milkminer cats from abduction by the robotic jelllyfish-like creatures. But killing the enemies is not an easy task to do. Sometimes there are many of them, and as you progress in the game, they take more and more shots before exploding, and of course they shoot at you, too. There are some timed powerups, they help to blast the evil seafoods - temporarily.

I really love the (pixel) graphics, the background music is great, too.
It would be great if the game was a little easier, or the buildup of the difficulty was better implemented.

+ Beautiful pixel graphics
+ Nice musics
+ Many kinds of enemies
+ Many achievements

- Quite hard, therefore sometimes can be frustrating
- Only 2 game modes

I'm using a controller, I think this (and skilled handling of the controller) is very necessary for this game.
