I played 1v1 which was fun. I'm sure it would be even more fun with four players. I think the theme was really ham-fisted into the game though. Being "invisible" was more like being invincible. The gameplay loop did get a little stale after a while as well, because there wasn't much to do. You could either go smash some boxes or steal your enemy's coins. I think some other power-ups and events could spice up the gameplay. That said, the game was really fun for the few rounds we played. Great work!

Sadly I had to try it out alone... but this was neat. The music was adorable too ^^
