A good, fun, pain in the ***
I enjoyed playing this game! I didn't have too much of a problem with the controls; mostly it was a matter of remembering to press space AFTER holding the direction keys. It might have been a little more manageable if the character didn't slide so far when just tapping the key once.
As for levels, "Sweet Dreams" was next to impossible. It was hard enough that you were working in complete darkness; never mind that the floors blew you up if you stood in the wrong spot (glitch?). If you had scripted the game to hide the cursor, I would never have beaten that level.
But overall, an excellent platformer. Difficult without making you pull your hair out. 4/5 and 9/10 from me.
