Pretty good for a first game. Some of the levels do get frustrating when you have to retry them (especially the counting one) and there is some jank with the 3d mode. Some QoL features like a faster speed to switch between modes (especially at the end) and a more consistent way to interact with enemies in and the 3rd and 4th mode would be useful. Also i didnt know it at first but the signs say different things depending on your mode which made me miss an important detail about the third mode.
But the last puzzle was really good and the endings are quite hilarious.
