I'm not able to re-create that bug. Which browser/OS/character were you using?
I tried to implement showing the vector field at some point but it was too distracting unfortunately, I could try again after the judging is done though.
I was on chrome/windows. By 'character', do you mean character in game? It was Lily on contract #25 on my second attempt of that level, I may have been spamming blocks a bit before it happened. I'm guessing here, since it went a bit fast, but I think I may have just beat the witch and that it crashed whilst transitioning to the cutscene.
Thanks! I'll try and test those conditions for future versions!
In the meantime, you could use Playtest Mode (in the options menu) if you wanna try the final boss again, though I wouldn't blame you if you wanted a break lol
Ok I did figure out where the bug was, unfortunately don't know how to fix it but you *did* win.
