The crash doesn't have anything to do with the graphics since it occurs when I click something, even on the lowest graphics settings. I can faithfully recreate it when entering the maze, going to the top-right lightbulb, taking the plug and bringing it towards the box. When in reach of the box, I can click the box, which doesn't plug in the cable I'm holding but just drops it because I'm out of reach. If I think click the plug again to pick it up, the game goes black. The same happens if I do manage to plug in the plug and then select the cable again to try to plug it out.
I very much enjoy the party audio depending on how close to the speakers you are to emulate the low frequencies traveling further. The low spectrum sounds very muffled though, maybe because you cut a lot of high end from them, so it's missing some attack. Is it possible the different layers aren't perfectly synchronised too?
Great job either way! Very successful jam entry I'd say.
