Glitchiest game ever.
You die randomly without even hitting spikes, and the game froze on me at level 31. The game has no learning curve - it goes from ridiculously easy to ridiculously hard and back to easy again. The levels seem like you just copied the same items over and over in a random fashion (which you probably did, I might add). There's also no save function, which is insane for a game with 40 levels that tends to glitch on every one.
Your game's horrid. Have you even played it?
At first I thought it was boring but its actually quite fun. Still can't get past the epic level, so I'm gem-bombing my way through the first easy ones to up my score ;D
The game's just too slow... I didn't feel any sense of action at all. You should be able to build more motherships and be able to delete your units as well. The enemy AI in arcade mode was pathetically easy, and in survival mode, there was no room for originality - you practically had to follow a set pattern to get anywhere. Creating units was the worst - even with a lot of metal ore, there was no way to use it all. This could be a lot better if it was tweaked a bit. 2/5
