From the games of this jam, this is one of my favorites so far. You did a great job, especially the levels are really well done! Animations are cool, the menu is also looking fine.
There are only two things you need to improve in my opinion: First, add a few environmental details to the levels so that the player has some help for orientation when trying to memorize where the spikes are. It does not have to be much! And second, change the color of the movable objects so the player knows right away that it can be interacted with. Apart from that ... keep going, you did well!
