Phew. Completed it. I like puzzles, and this was a challenging game which tested my limits. I had to learn the layout so that I could speedrun through the level as quick as I could. It helped that I stumbled across the fact that you can hold shift to move faster. That should probably be mentioned somehwere. I got tripped up several times on the slide puzzle, because I didn't know where the pixels on the border were supposed to go.
From a technical standpoint, I think this was one of the best games in the jam. I really liked the dynamic music, the flash light. The grid based movement reminds me of an old game called Sapphire Yours.
