Z key doesn't seem to work at start? P works to start the game but then I can't save by pressing P
Hmm, not sure what the issue is. It takes a bit to load after pressing Z - did you give it enough time to load?
Also, it only saves after every death right now. If you want your file to be saved you need to die first - sorry! Although it's a very short game so you might not even need to save
