Good Game...
But, yeah, it's definitly a piece of work.
I would recommend tightning the movement of Gridient Man, as the controls for him seem too loosey-goosey to actually get a really high score. Also, you really no to fix the whole 'refresh-replay' thing, but thats okay for a demo, and, besides, you guys are probably working on it, anyway.
Other than that I found no other glitches and it was a relatively fun game.
Good job!!! 4/5 8/10
But keep working on it!! I want the complete version NOW!!! XP
