Hi, thanks for the comments and nice feedback! Is it possible that you weren't actually stuck in the ground but that the character movement locked up after performing an action roll/sword swing or getting hit (stagger state)? That seems to be a problem that other people have been having and I am currently looking for a solution for.
So far there are just the two bosses you fought but we had originally planned to do a third boss, who is still coming! Hopefully with a bunch of bug fixes too :)
