Cute little puzzle platformer! The tutorial levels were well thought out and introduced the mechanics to me well. I also liked the art! Unfortunately I couldn't figure out the last room with the lever on the ceiling because I bugged out the game by pausing time -> unpausing time -> jumping and hitting the cube -> pausing time which caused the cube to float outside the level. Hope this feedback could help you fix it if ever you plan to develop this further and good job!
