Thanks for finding these bugs!
-I'm going to look into this, it might be caused by some error with when the amount is being saved
-I also noticed that only keys are set to 99, since the points are being added then I didn't really need to fix this, I'm going to also look into this because it's kinda weird
-If you mean that only one item spawned then I'm not sure what might have caused this, I have a few ideas but I'm going to need to check them
Currently the only ending is the bad ending from anger 10, so you can get it at round 1. I haven't made any other endings yet.
