Thanks very much for playing and your feedback spotting those bugs! I've managed to solve both of them so I'll be updateing the demo soon. It's wild that in months of testing those puzzles hundreds of times I've never seen that interaction issue before but at least two people saw it here within 24hours! It was a really tiny window of oppertunity when certain variables were set that caused it but thanks for pointing it out so that I was able to plug that hole.
What was feeling unresponsive about the gun to you? Was it the aiming feeling sluggish or perhaps the fire rate too slow?
