My Custom Super Mario Bros. Wonder Level: Spiky Ball Sanctuary (WonderLand Forest Jam level contest)

This level was made for the WonderLand Forest Jam level contest. You can download the levels pack here if you want to play them: gamebanana.com...
(Although my level sadly only works on the yuzu emulator for some reasons)
UPDATE: THE LEVEL NOWS WORKS ON THE RIUJINX EMULATOR AND MAYBE ON ACTUAL HARDWARD!!!!
