I felt that the bosses were strangely difficult after all I had to do to win the actual levels was hold down my mouse button and hit D. The second boss I will congratulate you on as I have never played a game where EVERY attack you had to evade in some kind of way or die.

boring

game is just too easy and lame. tried making it through lvl 2 but just couldnt force myself

Good but repetative

The game is enjoyable, the controls are simple and the graphics are good. The music is alright too. The only problem I found was that it got boring very quickly and I once I realized you could hold down the mouse for constant fire, I never let go.

The constant barrage of enemies isn't entertaining. If you try mixing it up, maybe stick in a story or platforms, or bonus areas. Something to keep you entertained. It's a really good effort and has the potential to be brilliant - you just need to jazz it up a bit.

could have been better

good initial approach, and soundtrack comfortable with the game. that's all about it, since enemies are acting all the same way, there are no power-ups of any kind and after a couple of minutes it gets definitely boring getting on always spamming clicks like hell on your mouse. Keeps busy for 10 minutes, tho, so thank you nevertheless.

Nice

Nice simple game love the pixel graphics muchley :)
