Nice game! The concept is really cool and on theme. The UI didn't seem to scale properly, and the level header did block button in level 5, but it was still pretty clear what to do. I would appreciate if there was a way to move faster, especially in long sections like at the start of level 2 and 5, such as by holding down left or right click to move quickly in the corresponding direction. Regardless, it was still a fun experience!
