Thank you for the detailed comment, I think it will help me a lot in later projects:) And I agree with all of them. Some of them I thought about myself, but since this was a school project I didn't have the time to go deeper into them. I don't think I will work on this project, at least in the near feature, but in later projects I will definitely pay attention to all the things you mentioned, and thank you again for taking the time to let me know about them:)
Btw since this game is inspired by Sokoban, you can look up the solutions on YouTube if you get stuck:)
