This is was actually my first Wayforward game. Their honeypot of cute Pixel art never pulled any of my heart's strings before. However I think this game has really nice (switching) mechanics a few levels in, so there's a bit of substance to it.
But fwiw, it's technically a puzzler first, and a platformer second. I don't even know why they bothered with adding a gun and shooting sections; It was mostly useless from my experience. I guess they wanted to fool even more people into comparing to Megaman X, since the art style is similar.
The game, as I everyone has been saying, is really short. It can be extended if you go for perfect high scores. I'm not gonna lie, I like going for them. It's where the game becomes more of a platformer, since you figured out all the tricky parts and now you have to jump & switch as quickly as possible.
But regardless of how much I enjoyed it, I couldn't get rid of feeling like I've been ripped off.
