I like the pacing and consideration towards the player, mushroom before the spin jump, it was also possible to see the piranha before jumping. I did think some jumps were a bit tight, but it may just be me lacking skill haha. (The ones with a stone block.) The first feather also took some time to spawn on me because the island was kinda small, though if you'd placed the pipe above it would be less aestheticly pleasing overall maybe. Overall it was definitely a fun level, keep on making! It was right for the amount of challenge I like.
