About this game

Are you ready to discover the world of Sky TD and immerse yourself into the fascinating tower defense game? You have to create your own towers to defend your island in the sky and stop the invasion of evil aliens – and it’s going to be fun!

The game was developed by a small indie-team of the TD fans, that is why it is so amazingly atmospheric and combines the best elements of the tower defense genre. Exciting game process, smooth gameplay, nice graphics, and ambient music help you to take a little vacation from reality and teleport to the sky islands, where the real battles are unfolding. Create a defence strategy for your flying magic kingdom, earn crystals and upgrade your towers to strike back little evil villains, who will attack you again and again.

Special game features:

● 50 levels
● 5 types of towers
● 3 levels of the tower upgrades
● Several enemy types
● Levels with the endless mode
● Free access to all improvements and levels.
● No Pay-to-Win.

All enemies have their own unique features: from sneaky midgets, to protected muscleheads - they’ll make your sweat while you are defending your realm and getting to the next level. Destroyed enemies leave behind crystals, which allow you to use lightnings against the invaders. Developers don’t insist on buying crystals, don’t demand any donations and don’t spam with ads, allowing you to complete all Sky TD levels for free.

Remarkably compelling considering how simple it is, although if I had one complaint, it would be that it needs some sort of encyclopedia, or some other way of introducing new towers and mechanics. The game never explains what towers and their upgrades do, so you just have to buy them and figure it out for yourself, which can be annoying. Same for enemies, blue creeps are immune to slows, which makes me wonder if other creeps are immune or weak to specific towers, but there's no way to find out.

Hey! Thank you for the review. I'm totally agree with you about encyclopedia :) The game needs it and I'll add it for sure. Just don't have enough time for that.

Minimalist style of TD with cute lil monsters. Might be confusing if its your 1st tower defense game, but if youre familiar with the basics (ice effects, splash damage, upgrading and selling, et c) you'll do fine. Very few ads, and theyre the kind you can immediately click out of. Super cute, relaxing, but still challenging game. My only complaints would be the lack of zooming in/out of the map (you have to scroll to see different parts) and no way to speed up/slow down waves. Well done devs!

This is the one of the best TD games I've ever played. I wish I could leave a thorough review here with feedback but there's not enough space. The ads are non intrusive and short. I paid at the end just to say thank you for the great game. The game is challenging but fair. The fast forward is an excellent speed to allow you to focus on strategy. I was able to complete every level with 3 stars without using the bomb thing, but unable to do so without any lives lost. Dev, is it even possible?

Hey! Thank you for so nice review! :) This review/answer space limits are so awkward. It's possible to complete any level without using crystals and losing lives. I've tested it throughly before release the game. But to be honest some of the levels took me extremely long to find the right way :) Feel free to ask me for levels tips/help by email ;)
