This was a lot of fun and has huge potential, I also loved the way you made a dynamic main menu. And the moving mechanic is something I've never seen before and the art direction is on point. The general theme kinda reminds me of a mix of Mario and MegaMan but still with its own twist. The moving mechanic was cool, but at times it got a little annoying having to wait for my energy to regen, maybe you should add battery pack items that you can pick up, specifically after you jump over some spikes, cause otherwise I'm just kinda sitting there awkwardly and it's kinda boring. Maybe I'm just too impatient lol. Also, the levels seemed a little too difficult. I couldn't get past the 4th level and after a few tries I rage quit. It would help a ton if there were checkpoint(s) so the player wouldn't have to play the whole level again.
Overall it's a good game and has lots of potential, it just needs some things worked on.
