1-1, Castle Escape. I've reviewed this level before, but for the sake of this series I'll be running through it again.
First problem that jumps at me is there's a large amount of enemies in a fairly tight corridor, and you're not given any sort of powerup until afterwards. It's not an issue that makes me clench my buttocks but it's still an issue anyway.
Next issue is this hole.

See how inviting that hole is? It jumps out as you as looking unusual, since it juts out at both ends. Let's jump do-

...ok
Pretty major issue there, deliberately fooling the player into killing themselves. Easy fix, either make it not stand out as much or make it actually look like it will kill you when you jump down.
Other than that, the level's pretty good, the tight corridor didn't feel claustrophobic and it's generally not that bad. The flow between the two sections is a bit awkward though, since they focus on different enemies. Overall beyond a few design hiccups it's not terribly flawed.
1-2, Bowling Calamity.
Aside from the collision bugs from the bowling balls that are all over the place in the level it's pretty good. Not sure if I like it being right there at the beginning of the game, but it's in no way an inherently flawed level. The sprites it uses, maybe, but the design is spot-on.
Why is everything grey though? The ground, the background, the buzzy beetles, the bowling balls, practically everything but the swoopers and lava is grey. It makes it a little visually monotonous.
1-3, Red Hot Swim.
I'm sorry but the second half of the level should just be scrapped and redone. I can barely get past even the first part of it at all, in fact I only did it once. You wait and you die, you jump and you die, you don't jump and you die, you can barely do anything without dying. It's incredibly frustrating and unfair, especially with no midway point in the level at all.
