Thank you for the feedback! I really appreciate it :)
Thanks for the heads up! I did actually account for the softlock you mentioned; I made it so that the enemies can't get near the checkpoints, in the same way they're stopped by the torches. Not the smoothest solution I think, but it works. They still do wait in there at a certain distance though, so I'll definitely keep an eye out in case anyone does find it too difficult to get past them at that point.
Glad you enjoyed the game!
