This was such a creative concept and the intro animation was excellent! Reminds me of that one Dexter's Laboratory episode where he gets stuck in his video game system as well, haha. I think the platforming controls need a bit more tuning, though - the platforms felt really sticky, and that combined with the momentum required to push blocks made it really hard to be precise. I also kept forgetting to dismiss the contrast adjustment menu, which was a bit annoying. The laser level seemed to require a level of precision in positioning beyond that I was capable of inputting, unfortunately, so I didn't manage to play until the end, but overall I really enjoyed how creative and stylish this game was!
FWIW, everyone else has noted the spacebar reset issue already, but based on what I observed, it seemed to be that if you ever clicked the reset button, that bound spacebar to the button (since I assume space and click are associated together). This binding would go away between levels until you clicked the reset button again.
