Alright, now that I'm unbanned, I've come here to complain and give you some HELPFUL criticism. So this is a helpful bump.
First my complaint. I'm not really that impressed that you took the project name "Shadow Star", when in fact, I had that project name. I haven't posted the project around here because I took a break from it for a while, and nobody commented on it the first time around, but I'm still working on it. I can even show the logo I made about
7 months ago, the same time I made the project.
Now for the criticism.
First off, let's take a look at that grassland level. I'm not a huge fan of the green hue you gave the graphics. It looks good if it was a toxic swamp or toxic cave type of level, but it honestly doesn't fit
at all with the grassland theme. The level design and background placement looks fine, though. Also, the picture below:
That gimmick with the edges in the center don't really look all that nice, honestly. My main complaint though, is the colour hue, especially the way how Mario and Luigi are are incredibly brighter/less saturated than the others using this hue. That's really my only complaint is the hue. Also, saying that you recolored everything yourself in this level honestly isn't too impressive, because anyone can go into Paint.NET and add a Hue/Saturation adjustment without extensive work. I'd be impressed if things were actually different colours, but this hue isn't too impressive to be truly honest.
Now the, uh, "desert" level? I like the graphical choice somewhat here, but the yellow grass doesn't really symbolize a desert, more like a Savannah. The hue returns here, but it actually fits a bit because I can see the setting sun, whereas there was no signification of why there should be a green hue in the grassland level.
The hue effect on Mario and Luigi return here again, and the saturation/brightness is too high again, it should be toned down a little. I like the Kuribo Shoe Roller Coaster gimmick idea, but I'm curious as to how it works out. Other than the yellow grass and the hue on the players, it seems okay for a desert level.
Third, I saw somewhere that you said all levels will have a hue? I don't really like that idea, and I suggest you disregard it before you start the next level. The effect with the setting sun hue in the desert level looked good, and if there was a level at dusk, that would make sense as well, but otherwise, I would refrain from doing any type of hue, especially like the ones seen in the grassland level.
I really hope this review is helpful, and I wish you good luck on this project.
