Ok, so right off the start, I thought I was the stone and when I moved I thought the world shifted....then realized I was the guy, who basically the same color as background. Probably should make background different color or main guy a different color. Then I thought I couldn't get up until I realize I had to move the stone myself. Then I thought wow this interesting so I make my own way.... Then I realize I could just sit on the stone and move the guy around and collect all things in the room with one stone which basically breaks every puzzle after that because you just drag and drop the 1 man on 1 stone everywhere in the room.... so this could be interesting but if man is on the stone you shouldn't be able to move the man and the stone together , only the stones that the man is not touching would be my main core element change if you want to build a stepping stone puzzle thing..... Hopefully this helps....Stopped playing after scene4 because of this break in mechanic. Not sure if it got better or this ability becomes restricted i don't know there is an idea here you just have to explore it deeper.

I think the concept was great! I'm not quite sure if this is a metroidvania, but it was a really fun platforming challenge nonetheless :) Especially considering how you can challenge yourself by choosing not to use the arrow keys to move. (By the way, since this game is controlled mostly with the mouse, it might make sense to update it to allow the use of the WASD keys as well, which feel more natural combined with the mouse.)
