I|m sorry but I didn't like that one.
It was too dark for my taste, most of the time I couldn't see where i was Jumping. The jumps felt not 'reliable' and I got stuck in the boxes. It was not clear which boxes (and other items) you could jump on and which were only decoration.
So in the end it was just try'n'error to find the exit and it felt more like work than like a game.
Nevertheless you made some pretty effects with the light renderer and particle effects.
