I apologize for my late Response. The slime switching is an unfinished Idea, which doesn't work yet. Thank you for finding the softlock bug though.
Regarding The sprinting Key - I understand your problem, kinda. I am Just Not able to control The Shift Key while pressing wasd, resulting in me always changing the sprint key to F If possible. Nevertheless, I understand that is weird for the majority of people. I plan on making personalized controls in order to solve that issue for everyone. But seeing that I am inexperienced this wasn't possible During The Game Jam.
Thank you for your Feedback!
