I wouldn't change much, I like the game a lot, seems like its well polished. I think it would be nice if you had like a 1 second grace period after the blue pellet wears off, I can't keep my eyes on the side of the screen all the time when I'm trying to move.
Bit close to Motherload, but its not exactly the same at least. I like the little sound effects, but it would be nice to be able to turn off the music without the sound effects.
I beat the game before the badges, and now when I go to see the credits it just goes to the demo, and now I can't get the "Have a Nice Day" badge without beating the game all over again, can you do something about this?
