Hey there!
I have not had many complaints concerning that, however, I plan to add a separate (autosave) save slot and manual save slots in the future. I understand and recognize it as a... well my fault for coding it that way but it was a design choice to simplify this core element (saving system), so it is more robust.
oh yay! yea a separate autosave system would be great, i don't mind redoing certain parts of levels if it means i dont accidentally autosave over my previous stuff. also makes it easier to try stupid decisions without having the autosave keep me at the teleport thingy when i die from said stupid decisions. thank you for taking player input!
