Was looking for a decent tower defense game, then i came along Ancient Planet. Levels are fun and upgrades are pretty decent but boy is this game a GRIND. Each continent is tougher and tougher and will leave you needing to go back a play the earlier levels over and over. I didn't mind this as i love TD games. Overall for Steam TD game ill gladly give Ancient Planet a 8.5/10 FUN STUFF

This is a fun little defense game with enough maps and upgrades to keep you playing for a while! Some upgrades are a little lazy though, like 10% more damage per time you upgrade. You build a base, which will gain energy or points for you to use for building towers, and other defensive things like land mines, stones, and slow turrents.

Theres slow and fast enemies, some tanky and some weaker ones. You have to plan ahead and adjust your strategy depending on what kind of enemy you are up against. Towers attack fast, but doesn't do much physical damage, for example. You can always see what the next wave will contain of.

Ancient Planet have a story, but it's very simple. It's you getting attacked by some kind of robots and aliens and your job is to defend your big building. Some text-based story in between the missions, but its still the gameplay that keeps you playing.

Is the game repetitive? Maybe a little. In the first missions they introduce a lot of new things, which keep things fresh, but in later levels I would say it's more repetitive. Game runs perfect though, and lets me move between my two monitors without the game tabbed down. It also automatically pauses when you click on your other screen, which is neat. Options are overall good.

This is something you should look into if your interested in tower defense games. Graphics looks good and the game has a helpful tutorial to get you started. This is quite easy to recommend, since the price is fairy low and the game is solid.

***Written using a key provided by the Developer for review purposes***

Ancient Planet is a tower defense game set on an ancient alien planet. The missions take place over a number of small islands and as you progress you encounter new enemies but you also get new ways to take on your enemies. You are granted rubies/gems depending on your performance in each mission which can then be used to upgrade your towers for future missions.

+The art style is gorgeous and everything in the game is well designed
+There are a variety of towers which are unlocked as you progress
+Towers can be upgraded, each upgrade level grants more range, more damage and more firepower
+Quite a lot of different enemy types
+Nice, relaxing soundtrack
+You can increase the game speed if things are going to slowly
+Towers target the first enemy in a line, not the one closest to them
+Funny cartoons displayed during the loading screens
+Good sound effects

-No graphics or resolution options
-You can't target specific enemies with your turrets
-No difficulty settings
-A couple of enemy types are overpowered
-There's nothing unique about it when it comes to TD games


A solid tower defense game with a great art style that's held back by it's lack of originality.

I usually don't write any review, but this tower defense, for a mobile port, is great : it reminds me of Prime Defender with the upgrade of the towers... Graphics are charming and the comics style cutscenes in between maps are amusing. Music is correct without being impressive.

The difficulty is good without being too complex, because of the small maps. And even if your constructions are not optimal the first time, as you gaining precious gems to upgrade the towers, it doesn't really matter : you can retry as much as you want.

I recommend this game for all the Tower Defense lovers!

The game looks decent and is fun to play. While it starts very easy the difficulty rises up to the point that you get completely stuck and cannot continue. The difficulty of the later levels can only be overcome by grinding skill points and the only way to do that is repeating earlier levels again and again and again.

The successful completion of a level earns you gems (skill points). If you fail to win you get nothing and winning a level you already played before gives you far less gems than the first time.

The game has many positive aspects that all become irrelevant because of the endless grinding it forces you to.

Can't recommend it right now. I'm on level...8 or 9 out of 35, and it gotten so difficult that I can't finish the level after many attempts, and I refuse to go back and replay old levels to get more gems for upgrades. I'm not exactly sure what the difficult scales with but after upgrading a lot of towers in the upgrade section, I'm having a hard time even beating old early levels to gain more gems. I'm not down for a grind. Sorry game, you lost me. Very sad too because there were a couple of inovative mechanics. Maybe I'll pick you back up down the line, hopefully the devs will have tweaked the difficultly stuff.

This game is actually a really good deal. Im 7 hours in and Im not even halfway through the campaign. This game offers very challenging maps, currently stuck on map #14. Great graphics, comic strip scenes, and music. It also offers survival mode and many towers, base, and special weapon upgrades. Very nice game, 8/10.

As tower defense games go, this one is very basic and run of the mill. While it doesn't do anything new or exciting, it does have everything a typical tower defense game usually has: towers you can unlock & upgrade, new enemies & behaviors, an in-game encyclopedia, and a rating scale (1-3 stars) that is awarded to you based on your performance. Towers can be put anywhere, which is a nice touch (factories must be placed on deposits). You can also replay levels you've beaten to earn more gems (to upgrade towers), though at a reduce rate. All in all this isn't a bad little TD game, though it didn't "WOW" me in any particular way. Still, I enjoyed my experience nonetheless.

Moonlight Mouse first Steam Game is a interesting tower defense game. Sure its not revolution/ evolution but its deserve his place. The story is telled in short messages before every level and its okay enough. The graphics are for a low budget indie game fine, the enemy development is fantastic, sure could have a bit more like more boss enemies, but its really great, the tower could be a bit more and have more different attack types (elements like water, fire, lightning, stones, lasers or something but for a Indie Game its great. The upgrade system is a satisfied extra, but there could be even more upgrades, starting cheaper and the expensive ones get more effective so for each tower getting 20 updates that cost not to much, but i am happy with that one that is given. The level design is easy but everyone you need to start new to destroy buildings and try to find the best positions for your towers. Last point are the achievements, its great it has so many, but there could be even more like buying all upgrades, buying all upgrades each update part (tower, 2nd weapons, baseparts) or getting all stars or killing 10,50.100 tanks and not only 100 tanks, but its only a very little critic point. So i give this game 93 % for tower defense fans, 86 % for normal gamers and because its a bit hard in the mid and end levels and has no difficulty levels (easy, hard) i give 73 % for casual players (because maybe you need to farm some upgrades and that takes a bit and frustrating). For 5 euros its a cheap game, even if the main champain has only 35 missions, but you cant rush from one to another. 2 last point i miss is that the game has only normal speed and extra speed (good extra) but sometimes i wish a bit more extra speed even then because long ways and slow enemies or a 3-5 second rewind option for mistakes redo or a slow motion, but its fine, i enjoy this game and for people that want a challenge try to do the levels without a upgrade and i miss a bit highscores in games (own, international for every level and normal/ surivival). Thank you for reading.

Ancient Planet (AP) is easy to overlook as just another standard ol’ school tower defense game. It does come off as rather generic, not bringing any new elements to the table, but looking past this the large number of levels do offer a good challenge that is fairly well balanced.

That balance will vary depending on which unlocks/upgrades you acquire (you are free to choose what to spend your gems on), inevitably making some scenarios harder than others. I had two times (around 30% & 75%) where I needed to resort to grinding some upgrades to win the levels. As of the 1.0.11 patch, this grind has been alleviated by allowing better rewards on replaying levels. I was happy to see this change although it came a little late for my playthrough.
There are only two main offensive towers, each upgradable to unlock a further 2 specialised towers each. There is also the usual slow & boost towers. Although there are not a lot of towers each offers a larger number of tower upgrade options per tower. This approach worked well for the smaller map designs. Keeps it simple. Upgrades can also be made to your offensive & defensive weapons on top of the towers (as seen in the top tabs in screenshot).

Pretty much all the maps are small, only offering subtle scrolling up & down in places. There is no mazing with all maps offering fixed paths, normally limited to a couple of entry points. Most maps were unremarkable, but there were a good half dozen that were particularly well designed offer a much harder challenge.

I thought the 2D graphic designs of the levels has good depth, detailed & rich. Towers, enemies & their animations were low tech but clear & functional. My only real detractor was a bit of a strange lag when changing between fast & normal time sometimes which jolted the animations for a few moments. Sounds had a bit of that 8-bit flavour giving AP a classic feel.

Survival mode is locked until you complete the main campaign. Certainly a good reward for beating the game but it also means you cannot play the mode for a long, long time. I would have preferred to see Survival unlock after you complete the area (usually containing 4-6 levels). This would at least mean for the approximately 90% (roughy going by the achievement %'s) that have not completed the game, they could play some levels on Survival mode. Also, I can't seem to find any high score tables for Survival mode even though a score is given when you lose (not sure if I missed it or they don't exist?).

Achievements are not difficult, basically just requiring you to put in the time/kills/collects, but to get 100% completion with the final achievement called 100500! (Collect 100,500 silver units) is a big grind. After my 30hrs, I appear to only be 65% of the way to it!

Despite being a little grindy & a little basic, AP is a solid casual tower defense game offering a decent amount of content for the price.

Mostly good balance.
There's some potential to fine-tune balance even better. But that's a minor negative point.

Atmospheric and ironic arts. Authors are talanted.

Luring gameplay. Game is small, but isn't small comparing to other TDs.
Game is a gem. Good memories will remain about it.
I hope authors will make more good games - want to see them.

I was surprised how good this game is. Replayability is good as well. Hopefully they will make a 2.0 or add DLC for this one. (FYI on the main weapons screen, drag to the left and there's 2 more weapons)

Really excellent TD game. Graphics are great, usability is excellent, all very addictive. I felt it got exactly the right level of playability: you get eased nicely before things start getting challenging.

A couple of minor gripes. You don't seem to be able to select an individual enemy as the preferred target, which would sometimes be useful. There's a fair bit of grind to get the upgrades needed for the later maps - but I'm not sure I've played any TD game where that wasn't the case.

A couple of maps on the final level are really difficult and I got close to giving up. But it's so addictive that I persisted.

The game is fantastic and cheap as chips. What's not to love?

Awesome little game, better then Kingdom Rush in my books, music, art, everything is classic nice and clean Tower Defense. I highly recommend it , hours of fun,

I don't get the "grinding" reviews, I replay a few levels a few time as I always do to see and test different strategie and I never needed to "grind" and this game deliver, completly different strategy might work as well on the same level or completly fail.

Only gripe, why is FastForward only for 5 sec?? Please let me trigger this on and off at my chosing?

An enjoyable Tower Defense game with nice art assets. There is a bit of a grind element to it at times, and it lacks certain TD game features such as speeding up the interval of incomming waves and having to reactivate the existing speed up which does make everything faster apart from ability to call in the next wave for a bonus if you can handle it.

There is also a lack of proper PC settings menu, which should be part of any game that is being released on a PC especially when ported from mobile or other platform.

Some of the tower and weapon upgrades are a bit boring; e.g. 5% more damage on several consecutive upgrades.

Having said all that it is still a decent TD game well worth a try if you are into Tower Defense games.
