Thank you so much for the feedback and for trying out the game!
When you got stuck during the boss fights, were you near any walls? Did it happen after pausing? Or did it happen at random? I'm asking so I can perhaps more easily figure out how to solve it.
As for the controller text, it's something I'm intending on changing as well. The pause menu is temporary and so are the way the controls read whilst playing - for the controller anyhow.
All in all I agree with everything you mentioned and they are things I'll be working on fixing!
Cheers and Happy New Year! ♥
