Glad you enjoyed it! I knew about those first two bugs with the files, but I don't know how you got to day 16 lol. I think it should be bug-free if you reload the game and click play submitted games from the main menu each time, but I'm not sure.
There is some coyote time, but maybe I should've added a little more. The slightly slippery movement is somewhat intentional, but maybe I should've reduced it a bit. I was going for movement physics similar to Mario games.
