“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.

Key Features

Optional 2 player local CO-OP.
Branching map progression of levels.

Easy Mode - a version of Normal mode in case you found it too hard, with more health and easier enemies.
Arcade Mode - a special survival mode where you must collect gems to purchase powerups.
Depth based power-up systems which gives partial control on the type and location of the power-ups created (allowing tactical advantage).

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).

For those of you that remember the original Seaquest game (circa 1983), for the Atari 2600... Your little submarine was charged with the task of rescuing divers and blowing up anything else that stood in your way. (Loved it!) At long last, and many years later we elders of gaming and our whipper snapping next, next, next generation (I forget what the latest and hippest term should be...), now has a true and worthy successor!

Ohhhhh, the utter charming and adorable cuteness of the many cats and kittens in this game, should by no means detract you from the sheer fact that this is a bloody hard and brilliant Arcade epic! It's so awesome and so much fun, I barely know where to begin. Is it fast paced?! And how!!!! Will you become addicted?! Oh my yes indeed! Will you forget the world around you, and that you have to cook dinner for a hungry family?! *Cough, cough... errrrr I might have.... errrrrr a time or two...* Will your trigger finger be glued to the controller?! Oh yeah!!!!

Gameplay is divine. Graphics and sounds are wonderful. Storyline and plot are all about saving the cat miners, and undersea milk farms from destruction... Really do you need anymore than that?! Now be off with ya and have a blast me hearties!

Cute concept, brilliant idea... But it's ruined by extreme difficulty spikes and awkward design decisions. While the first few levels are enjoyable, and all seems well intially, the game quickly divebombs into frustrating and tedious territory.

- Great pixel art
- Decent amount of levels/content for an arcade style game and the price.
- Very easy to learn and control.

-Geared heavily towards luck, too little towards skill. The advantage of bullet hell shooters is that there are patterns and expectations. Players can develop skills based on what they learn from patterns. Not so here: enemy positions are randomized which creates a ton of frustration. One game you'll have red jellies congregated in one area, another game you'll be frantically rescuing the cats one after another.
- The player is woefully underequipped to combat the majority of enemies. They absorb a stupid amount of bullets and the power ups, except the two extra cats and the bomb, are faily useless.
- Half the nemies are programmed to dive out of the way of your vehicle. This may sound interesting at first, until you realize how much time you're spending chasing enemies that randomly move out of the way of your already underpowered weapons.
- Difficulty essentially equates to dumping increasing amounts of enemies around the screen randomly, often before you've even finished a particular wave of foes.
- The foreground art will regularily cover enemies and bullets making navigating around the map incredibly annoying and, again, make your survival a lucky happenstance.
- Bullet travel length is based on the direction and speed you travel, amking moving forward actual disadvantagous in most situations, despite moving being what you need to do to survive.
- Balancing looking up at the alarm and surviving while doding bullets is way too much to handle. There should have been any easy indicator or red arrow to show a cat is being abducted and the quickest way too them. I can't count how many cats I lost simply because the game expects you to juggle way too much visual information at once with so little direction.

It's really a shame because the first few levels promise so much more than what this game becomes. I can't recommend it when there are so many better arcade shooters in this genre available. Cute graphics and cats simply don't win out over undercooked gameplay.

< Disclaimer!! I got this game for free for reviewing purposes >

I'm Not a cat person but I sure love this game.

It reminds me of the old Retro Arcade games I used to play, And this one is undersea, which is weird because cat don't like water.

The game-play, You get power-ups to buff up your submarine And health pickups to .. you know .. heal, And a bomb power-up that auto explodes when picked up to clear the area.

The main goal is to not die (Duh) and defend those little kitties that are working the Milk Miners from being abducted.
Discover more enemies as you move further in map, Defend 1,2 or 3 milk miners it differs between levels, and a Boss fight at the last level.

25 Levels in 3 Modes.
Easy - Normal - Arcade.
I don't think I need to explain the first two, But Arcade mode is PermaDeath mode, Try to finish the 25 levels without dying once, Its the only one you get gems as money to use to purchase upgrades or heal your ship.
And an extra level Infinite Espresso which is an endless survival game but you have no Kitties to defend, Just fend for yourself.

Pros :
1 - Wonderful designed game, Very cool soundtrack, Animations And Effects.
2 - Addictive Style, That comes with achievements and trading cards and a leaderboard system for all 4 modes of the game.
3 - A challenging game and a blast to play with a local coop buddy.
4 - I really liked this feature when a kitty is being abducted when it says ( Meow ) To alert you, The sound comes from its place so by listening to my headphone I can tell where to go left or right without having to look at the Radar.

Cons :
1 - Its the type of game that will keep showing you controller buttons even if you are using a keyboard.
2 - Has no re-definable keys and the game kinda needs it for a keyboard user because the base ones are not that good.
3 - Forcing 1280x720 resolution is okay in the game it looks good but while using over-lay to chat it looks a bit blurry in my 1366x768 native resolution.
4 - It felt like some levels are waaaay much harder than the more advanced levels > as in level 10 being 5 times harder than level 15 ( my numbers are not accurate because I forgot which but you get the idea )

The butter of the review :
A Very colorful Retro Arcade game, Even if you're a dog person you'd still love this game, Its fun and challenging and gives you time to grind for achievements and The Endless survival map.
Recommending this for all you Retro shooting Lovers out there who'd love to get an adorable fun game like this.

Average Completion Time :
I'd say around 2-3 hours to finish normal mode maybe less on easy mode.
And it depends on you on how long it takes to finish Arcade mode because its quite hard.
And endless hours to get a leadboard ranking and to show how far can you reach in Survival.
