Yuu, here is an old level, ready for an new review.
Level design (technical)
This is a slightly hard level and most of my deaths were because of enemy placement.
To be percise, it was the bullet bill cannon placement. I am not saying that anything is wrong with the cannons, but the fact that they could hit me while i was crouching/small mario surprised me.
I hope that was your intention, because it bumped the difficulty up a tad, which made this level more enjoyable.
the first basin of water has escaping fish... :O
Also there is a ant enemy which has a gun(??) strapped to its back. I don't like that when he shoots, the bullet comes out of the head of the ant instead of the gun.
The enemy placement in the remainder of the level was really fair so that the player could just have a good time, instead of raging.
Speaking of rage, I fell a lot(this mostly has to do with skill) off of certain platforms/water, this might be to make it harder, but it would make the level more fun if you made the level so that you can fall down without dying. Maybe it is an idea to make the level more vertical so that you can just fall back on a piece of the level you already passed.
I, do not have anything to say about the switch section, it was good, not hard, and forgiving if you passed the checkpoint by making the green available from there.
Next up: the floating body of water.
I don't want to say that i hated the concept,but at 8/10th of the section it began boring me because of the repetitivity. The fact that you need to go through it a second time for the star was kinda original, but it did not fix my problem with it. maybe you could have added a vertical piece of level in that section to mix it up a bit.
i would give it an 7.2/10
Vibe
Let's see if the level's vibe fits in terms of background,graphics and music.
To really be able to judge fairily, I need to understand what the level is going for.
I personally think you, the creator, are going for a semi mario galaxy level so that point is which i will be judging from.
First, the background: It has dark, purple clouds and a deep blue sea. The purple clouds make the level feel kinda space-ish and the dark sea makes it feel like it is at night, even though you can not see any stars... (not the obtainable ones xD). This combination gives the feeling of mario being in another atmosphere, thus that he is in outer space (or that some impeccable apocalypse is incoming).
Graphic-wise (this is where the galactic theme is really coming out), this level is really going for it... purple grass, trees and giant ants... well, if that is not fitting with the space theme, I don't know what is.
Just FYI... I like all the colours together, especially the blue from the pipes/water and the purple from the scenery next to eachother.
Music: ... just when you thought this was a flawless level... I'm going to talk about the music...
When I listen to it I personally think of a industrial(slightly galactic) level. This level, on the other hand, is more of a nature level which could use some slow paced smg2 music from a water level.
That is the only nitpick i have on the music though, it is just a little too techno, even though it is relaxing.
Final result
Seeing everything together i would give this level a
7.6
I hope you make tons of new levels even harder than this, because i can see you can make some challenging levels.
Cya,
