Thank you so much for trying it! Your feedback really makes me happy.
My apologies for the bugs, I had too much trouble getting the re-centering to work fine, so I let that small bug of the player falling, I thought that was not so much a hassle because I usually play fast action games.. now I know that it is a hassle!
Did you curve the fireball with a lot of speed? I only tried it slowly, my bad.
I'm glad I uploaded for every platform to avoid that issues with installing something, even it it's webxr compatible ^^
Gonna try your game as soon as I can
