Thank you, I'm glad you enjoyed it! I intentionally hid the mouse and made the controls centered around it since I thought I during planning I might of implemented an inventory system. There is the alternate controls of arrow keys acting like the mouse inputs.
Apparently that bug has been plaguing users, and it's partial failure on my part explaining it. If you get stuck, hold shift + movement key(s) in the opposite direction of what your stuck in and that should free you. I've been playing with the bug in mind for so long it just didn't seem like an issue because "I" knew how to get out of it.
I hope this helps since there is still a bit more content that I put into it (and an end to reach). Thank you for your time!
