I thought I couldn't play the game since I don't own the cube but I'm glad the emulator works for it. Although it became very confusing the more I used it because the twist directions are not always the same, sometimes twisting forward makes my character turn, sometimes it makes them walk forward and sometimes it switches the light (so I ended up playing the rest on keyboard). I also couldn't really figure out what the hint system in the cube was, so at the end of the day I had to search every cell :( until I got teleported back to the starting location, where interacting with the tomb ended the game.

Nothing much to say about visuals they're good. You do know how to draw a creepy flower.

I think your idea of connecting the cube to a game is good, and I think it can be used as much more than a controller, so I'm hoping you develop this further.
