It's extremely polished, but I wish there was more explaining how the world worked with moving tiles. I got confused when things weren't moving the way I wanted to in a single direction when I was slamming against the pieces. Or what the end goal was to kill all the enemies and/or get the treasure. I kept progressing on death anyways, so I'm still not sure how I was able to do that. I tried to close the game to go back to the main menu and the game brought up a blue screen and it didn't change after that. All this can be fixed with a good tutorial level or two to showcase the mechanics more in depth. I hope you do more with this.
