-1-1: Could use some way to get to the top of the flag. Invisible blocks, maybe? -1-2: I like the idea branching paths, though there's this permeating sense of "where tf am I" -I did notice one brick-filled gap near that looks very much like it'd hold a secret but doesn't actually lead to anything -1-3: Clever use of verticality, good flow. You don't get lost much (or at least I didn't), which can be an issue with this type of level. -The midway point red flying question block ought to be set up to not spawn the mega mush (no real use for it in this area) -The last part of with the level with the big mushroom is sorta barren of gameplay. Could use some coins or whatever -I'd simplify the look of that last pipe before the flag because it kind of hinted that there was something up there -1-Tower: Unfinished, but I like what you've got going there. Just one thing: I thought the door at the top left of the first room was a secret room/branching path. I was disappointed to discover it wasn't. In my mind, the regular way forward would've been a pipe at the top right of said room (which I neglected to check on first playthrough) or something like that. You could do that -1-4: Cool out of bounds trick. Bit weird to spawn right under pipes though -I'd put the midway point powerup farther than the mini mario pipe, you can end up wasting it if you unknowningly hit the block before going in the pipe -1-A: That pipe after the fish spawns looks enterable, but it's not. Misleading. Also, tiling mistake: you didn't use roof tiles pretty much anywhere -1-5: No issues. Strong level design -1-Castle: Last starcoin is a cool challenge as big mario

2-2: I really like the visuals of the second area. The two backgrounds, plus the mix of mushrooms and clouds, works very well. Maybe move the secret room pipe to the right by 1 tile? Would make it easier to aim for.
