I'm not a fan of avoider-type games, but I like this one. It's simple and to the point, and has it's own little twist. Downside: cannot move diagonally, and the creeps spawn anywhere on the map, so it's only a matter of time before one spawns on top of you.
Again, very good concept for a game. However, I feel that it needs a level reset button as opposed to a "level rewind" button. I don't want to replay the level I just completed, I want to replay the level I can't beat... Maybe a level select screen/button as well as a level reset button?
Along the lines of previous comments...
It is too slow, and the music makes me want to gouge my eyes out. I find the gameplay (short but) enjoyable. If you made a longer version of this, I would play it. As long as you change the music. And maybe speed things up a tad.
Not terrible, but needs work. I think it's a great story, but the physics are rough, as well as the controls. You cannot turn when coasting. not a horrible play, though.
I like the novelty of the "collect the matching chips," but it seems like a straightforward upgrade system would work better. Also maybe dividing the game into waves, but i feel like that would be taking away from the gameplay. Good work though.
