it took me some time to get into and fully understand the mechaanics , but after that I really injoy it !!
the character swapping mechanic was cool and the puzzles were fun
I think some sfx and music would bring some more life into the game , also showing the physical barrier that prevent the player from walking throw the pumpkins ( and make it change it's colors depending on the current character ) would help explaining the game mechanics
over all great submission
