Because I would have to code that feature in and its a bit more complicated than just coding the game itself. I am not the most experienced programmer, Ive only been coding since working on this project. Also If I do a saving system there would be more additions like deleting progress, save files, and the whole system of how the game currently works would need to be redesigned. like for example what happens if u quit and its saved, next time u open the game where are you exactly supposed to spawn again? will you start at level 1 again? if not I would need to define spawnpoints or level startingpoints, it gets more complicated and I just wanna leave it where it is. Most people play the game under 40 min so I thought it would be fine. If not then I guess you will just have to do multiple runs, its just how it is now.
