-Weird logo -Decent level design, plenty of good ideas but also a bunch of empty space -Overly saturated 1-1 background, try less colors maybe -Decent music hacks -Many of your slopes (especially 1-2) lack the slope edge tile at the top of the slope -You really like 10-coin bricks huh -1-2 mimicks the original level a bit much (beginning, starcoin). Try to break away from the original level rather than building on top of it -1-3: P-switch coin bridge that leads nowhere (and blind jump on the way down) -Some camera issues, blind jumps and offscreen stuff (including unseen hazards, like the pipe that drops goombas in 1-1). Beware of overestimating how large the DS screen is -Try not to overuse the "starcoin above pitfall" bit, you did it thrice already -Big jumps in 1-3 leave you vulnerable to enemies like jumping paratroopas. It's manageable, but still falls in the category of "unseen dangers" -1-3 gets repetitive rather quick -At the checkpoint- koopa shells can't actually break these bricks, not on their own at least -1-Tower: If you jump on the big dry bones without looking you can get squished by the stone block, unseen danger again -That small room with the starcoin looked like a setup for the secret exit, but I guess not -Pipe that shoots you up into a starcoin: Backwards incentive, you have no reason to take the harder path (to the left) -Try to not make simple jumps outright require the height boost you get from gaining momentum -Did Bowser jr get charred -1-4: NSMBWii remake. Not much point to it -1-A: Oh, good premise. Since you went with water tiles though, you could break it up by adding holes in the water that the fish fall through -This level is a bit generous by giving you a fire flower right off the bat, though -Second starcoin is basically free, avoid that -Also, you could exploit the fact that the player can go into the water in specific spots and hide goodies down there (or maybe a warp pipe?) -1-Castle: That jump off the first tightrope, immediately followed by a dry bones, is quite awkward. It'd feel intentional if not for said enemy. I'd say shift the dry bones to the right by several tiles. -I assume that huge block is meant to move, but you misconfigured it -Unseen thwomps. I'd say make the first thwomp visible, the rest can stay hidden above view -Free starcoin again -The tightrope after the thwomps can make contact with the lava- avoid that if it's unintentional (doesn't feel intentional, unlike ones later in the level) -Big dry bones gets stuck on the tightrope edge -Unseen thwomp again. You could add some hint to their presence- like explodable blocks right above the pipe maybe? -Oooh I get it, it's a dark bowser/jr retexture
