Hi! The It's a bit chaotic; so much is happening that I'm not sure what will kill you and what won't. I suggest simplifying the mechanics a bit and introducing them gradually. For example, the red blocks could be the first obstacles, and then the columns after a while. And make it clear what the objective is, what items can be collected, and what they're used for.
Anyway, it's a good start, and I congratulate you on your work. The art is good, and it seems there are several ideas; they just need to be organized a bit.
Cheers!
