I am giving 5/5 on everything. For me the main highlight is how the level design is connected to the story but it's not pushed forcefully onto the player, it's up to the player to notice it. The mechanics are also really satisfying, they are quite new to me, but far from confusing, after a few seconds you are sure to figure it all out. The music is also really good, simple, but that's how it should be, since it very well compliments the visuals and the general feel of the game. I don't even know what to really improve, other than the obvious stuff for a game jam - adding more content, adding more polish etc. I did once get stuck under the terrain, so maybe check the collision shapes to make sure there aren't any holes in them. Great great job, would love to see a full version of this
