You're absolutely right. I'm sorry there isn't anything else to do, I didn't really have a free weekend unfortunately, and I spent too much time experimenting with stuff instead of creating something playable. Thank you for pointing out the idea of a puzzle game, I think it would actually fit perfectly with the orthographic view as you said, it could also have some parkour too. I'm looking forward to making a full game out of it.
Have a great rest of your day!
