Thank you for the game! An autosave to each floor would be helpful.
There is a feature that helps you pass levels that you have previously completed, but from the video you uploaded I realized that it is not clearly visible to the player. When you die and start the game again, ghost feet appear and guide the player to the exit. The feet will accompany you to the last level passed (e.g., if you passed the first three levels and on the fourth level you die, the feet will be available until the third level). I am already modifying the code to make sure this feature is clearly visible from the first time.
I preferred this solution to the autosave one to emphasize in-game death. If you get a chance to try the demo again let me know if you like the effect and if you think it can replace autosave 😉
