A Sonic-style beautiful simple level. A remake of "Labyrinth Zone", but we don't have a labyrinth here, this time. And we don't have a Sonic, who can't breathe in the water. As Mario has this advantage, you have used and abused of this moving water gimmick. And it's what made the fun in the level. I really liked that. It's a easy level, but this isn't so easy really. When the water comes down, you can have a stupid death. And you can't do big efforts to avoid this. The reasons: Some parts have some crabs. The player will lose your mushroom (or your life) if he touch in the crab. Talking about mushrooms: This level needs more power-ups. At least a power-up in the first step.
Design - 3.80/5
Simple level, but very impressive. The water gimmick is the main ingredient for this recipe of fun. But this level have some problems. Not a huge problem, but it affects the design: The cut-offs, por example. I can't talk about the statue bug. But I need to say about the spikes. In some parts, if you touch this spike (without water in the most part of time), the spike will push you (forced) inside a wall or inside the spike. It's weird. I suggest you to fix this. I can say too that some parts are hard to avoid when the water goes down.
Placement - 3.50/5
I don't have any complaint about the placement of coins or enemies. Except from one thing: Some parts have a lot of enemies, and some parts can be hard to avoid when the water goes down. And I think you can remove some spikes too. The Dragon Coin placement (as a Moon Coin) is good too. But I think it's better if you place the fifth Moon Coin before the Star.
Atmosphere - 3.80/5
You built an exciting atmosphere of a simple Sonic style. This don't have the most original gimmick, but this are enjoyable. I had fun while playing. And I had a feeling that you have transferred well the Sonic ambient to the level (except the maze of the original level, but that don't will count in your final grade

). It's a very good linear level. With a powerful gameplay.
Aesthetics - 4.15/5
Everything matches. Anyway, three things I've dislike: The water (I think this is a little strange, but ok, It gives a nice atmosphere, but I suggest you to do some adaptation, I say this because it leaves some blocks really odd); The cut-offs/bugs and the spike problem.
Overall -
15.25/20 or
7.625/10
