Pretty cool concept! It took me a little while to figure out what to do, and for the life of me I couldn’t get past the third wall — until I finally maximized the game to full-screen. Then I could see farther into the distance and grab the cube. I liked the clapping mechanic for lighting up the room, though it didn’t seem to affect gameplay much, which threw me off a little. With some tweaks to level design, I think this could be a really fun game, so I hope you add more to it.
