Thank you for playing and commenting! I felt the UI was a bit too big, but after I shrunk it it was a bit too hard to read, I think I should have put the selection menu to the side so it is a bit less intrusive. The problem about not being able to press the button was something I faced when making it, I had an event at the end of their refilling animation to make them be interactable again but if I pressed it too quickly it didn't work! I spent a while trying to make it go away but I almost ended up breaking it more! I'll try looking for a reason that's happening but for now I'm just glad I managed to submit the game.
Edit: I just saw you said about making it into a full release, thanks so much!
