Really awesome fun game, ofcourse the lag is the problem, maybe spawning masks everywhere the player goes might not be the best way of doing it, but regardless it is still amazing! Also, a sweet ending :)
Yeah, it wasn't the best way, and I'm definitely fixing it later. But it's a game jam, and sometimes you just have to rush the mechanics in. I'm glad you liked the ending; I put a good degree of effort into it and it makes me happy to see that it paid off. Thanks for playing!
