I kinda like the idea of this game, but I was sadly unable to test it since I only have one keyboard and no controllers. I didn't see any other way of adding players to the game, so the game ended up just being a single cube flying around the level.
I was able to gather what the game is from the game page, the other reviews and how I could control the cube, and it seems like a neat idea!
The lack of sound really drags the game down I think though, even if it was just some royalty free Kevin Macleod music or a little blip when a player dies or goes off the map would be neat.
But I could see this being improved into a pretty fun game, good work!
