Nice game! Could you elaborate a little more about the algorithm you've used for evolving enemy upgrades? (representation, operators, etc...)

^It basicly jsut sucks in the list of upgrades/levels that the two best performing enemies of the last wave had (based on life time, kills add 30 seconds). And then semi-randomly divides up their upgrades to create 4 new enemies. Those 4 new enemies then have a random selection of upgrades removed or moved down a level, then all 6 enemies have upgrades randomly added until they reach a certain "total cost" for upgrades. (This cost increases each wave, resulting in larger enemies)

Nice game but movement is a bit hard - cannot hit the angle I need atm.

Very cool game. Feels very polished. Unfortunately it crashed about 10 minutes in.

I enjoyed it, and thought it was decently fun. The biggest problem I kept having was lining up shots. It might have been useful to separate firing and movement (maybe something like Binding of Isaac or Realm of the Mad God. Other than that, it held my attention for a while, and I really enjoyed the music.

I really liked the feel of the tiny jets and the backing graphic was cool. Good music too! Well done :)

Very cool game. I enjoyed the music.

Excellent way to use the theme & great game too! Limiting movement and firing to 8 directions made it a bit hard to hit things; I think it would work better if you could move & fire in any direction.

Overall though, very nice work. Oh and good job on the music too - really liked it!

Great music, great graphics. Balance is all off. I spend $200 on blasters up front, and don't spend anything else, saving up for missiles before getting wiped out by the hyper-advanced weapons of the "evolved" enemies. Level one, I'm losing because everyone but me has a deflector.

Really good entry! I liked everything about this game - quite fun. Really hard though.

The AI is nifty - at first I thought I was playing against people. I'm not sure why.

The particle effects after the first two levels started to cause some serious slowdown. Otherwise, a fun game with good music.

Nice game. Feels very polished, I like de buildings. Please, rate my game.
