Nice game, it fits theme really well and the gameplay as far as I know is very original. Because of that same originality it was a bit hard to understand how to play at first so I feel like such approach gives you additional challenge of communicating all the mechanics to the player. As far as that goes all I can suggest is more interactable tutorial (but of course it's pretty hard to do in such short time, so I understand why it's not included) and also some visual highlight of more important visual elements (I mean arrows that indicate directions, as it was biggest struggle for me to notice them since they did not visually stand out at first). Besides originality, gameplay was also pretty fun and satisfying. Bonus points from me for using very basic shapes to create decent graphics and for making the game available on mobile devices.
