Colossorama

Pretty fun but the lack of a larger campaign structure and unlockable items sort of flattens the experience for me. Also, it's a bit disappointing to feel happy with my current weapon then be forced to replace it with a lesser weapon later. (The player should be rewarded for good performance, not penalized.)

Great starting concept. But what do you do after 200 waves of slaughter?
I guess, just keep slaughtering...
