Good.
Got thru it easily until like 7 screens over where you had to unlock 3 bars up and at least one bar on the bottom or top, 2 screens after the low gravity. (Dunno how else to explain) Anyway, nice creative game. My fingers are tingly after trying to stick to the walls on the sides.
simple
like i said
also it could have been a little longer
I went for simple. Complexity doesn't make a fun game necessarily. I kept it short to make it, "instantly replayable." I wanted to give it the quality of being able to be played during a quick break at work.
Potential...
It doesn't have the physics you'd expect or need for a GREAT platformer, but it's still GOOD. Also no instructions, the graphics are nice, but if you made the outlines a bit thicker. Try to grab a more "Nitrome" style and it'll be awesome.
