I assume that there's supposed to be more than a title screen? I can't click (or otherwise select) the "Play" option.

The graphics are not good, it feels like those Powerpoint 2003 images and the pixel art is so. bland.
The gameplay is bad the characters are really simple, boring and painful to look at.

Sadly, i think this sould be bl4mm3d.

I like pixel-art as much as anyone, but a lot of this just hurts my eyes while playing.

The general idea is good, a simple platformer where you attack enemies and try to not get hit.

I like the gallery idea, it reminds me of super mario 64.
Sadly, walking in the gallery feels clunky and unresponsive.

Also the wall climbing feels off. As of now it seems like I'm just performing multiple jumps several pixels away from actual walls. maybe add an animation for wallclimbing?

Lastly because of the background some floating platforms are hard to see, this could be easily avoided by giving the platform a different color.

All in all I like the idea and I feel like it has great potential. It just needs a few minor fixes to make it perfect.
