Wall to wall jumping pisses me off, half of the time I get a pixel far from the wall before jumping and the "wall jump" doesn't work. Can't even get out of the level 2 pit...
I'd love an "undo" function, a way to rotate blocks of components and another key than shift to switch between tools (because for some unknown reason my flash player fails to detect shift properly).
Good game, though the keyboard setup is a bit awkward for AZERTY keyboards (either move with right hand on arrows and left hand for jump/dash/wallwalk or move with left hand on arrows and right hand on the mouse for mouse-looking).
Want to buy options to change the action keys. Some levels requires to control exactly which portal color to launch, instead of cycling through both colors. And this isn't possible with an AZERTY keyboard.
As my eyes get used to the scrolling, everything that's actually fixed seems to slowly move in the opposite direction. Very funny game anyway, with lots of control options !
The colors are too bright, it is sometimes hard to tell the difference between green and yellow, and green and blue. Moreover, the tower being completely opaque, it is difficult to see how far it is from pills behind it.
