Oh! There's a badge for a BPM upgrade!
*Searching for the BMP upgrade*
Here it is! Better make sure everyone's out of the house at night with all the lights off!
*Cries*
The enemy variety is great (The enemies are also very innovative. I've never seen, in any other game, an enemy that can spit out its own babies that stick to you and slow you down, then grow up after you shake then off... and I've played a lot of games.) and the difficulty ramp is perfectly balanced... controls are easy and intuitive, graphics.. well, graphics could use a little work. (But hey, graphics don't make a game, now do they?) Oh, and this game is funny. The humor in the award descriptions is awesome! Now, for ideas for any kind of sequel you make (which you SHOULD!!!): RPG elements, or at least different weapons.... Sick of the pseudo-Buster Sword, anyone? How about a hammer? Or a ranged weapon? Maybe a story mode too, because judging by some of the stuff I've read in-game, this seems to take place in a world where some weird virulent life-form is infesting the planet....
