so..
A nice shoot 'em up game, with a long story line I didnt bother myself with. The game itself is pretty easy..... actually its to easy, I didnt die once and I was on planet 6 or something. The game gets to repetetive and to easy. when you get some nice weapons and shields its gets even easier and there is no challenge to it anymore (not that there was any in earlier levels).
The weapon and shield inventory is crap. at least make 2 separate places for shields and weapons, now I have to scroll through everything to recycle and to see the stats.
redeem is a nice thing, but I never got something nice out of it, so for me it was worthless. The enemies dont really change, sure you implemented more diffrent types of enemies at later levels, but somehow they werent really more difficult.
I dont know what you were trying to do when creating non firing waves, those are just stupid and dont contribute to the game.
The bosses seemed similar to each other also, again they were very easy to kill and never was I cornered or near death. later bosses were killed even faster because I had better weapons, it didnt seem they got stronger or anything.
so all of the above made the game very repetitive to me and after so many levels of shooting and not even trying but still passing levels I got bored and quit.
the gameplay is nice and so is the style, it wouldnt surprise me if it makes frontpage, but for me its a 5/10 2/5 mostly because I expect more of your 'team' (diseased productions)
