Hi, thanks for finding me again :-)
I did not know that, and I didn't know shift is the default run key for most games, I will keep it in mind in the future and change this. I trapped the player in level 3 to introduce the R for reset. You're right, one shouldn't do this too often, unless you want to lose the player. The story was a last minute change, so yes, this could really use some polish.
Thanks for the helpful feedback and the nice words.
