Thank you very much! I'm still pretty undecided about putting in an undo button. I feel like I'd need an in-universe, diegetic reason for it. I am still unhappy about the "press r to restart the level" text, but I didn't know how else to explain it.
"Management: PRESS THE R BUTTON TO BE DIVINELY REBORN INTO A TIME WHERE YOUR MISTAKES HAVEN'T HAPPENED YET.
Little Gray Worker Blob: ...wtf is a button?"
I was thinking maybe changing it so if a movement key is held down, then it starts moving you slowly like currently, but speeds up after 2 or 3 tiles. Does that seem better?
