Seems like it's going to be an interesting game, for sure! I played around a bit and found a few things. When first entering the level, the character will seem to be stuck in the ground, and the jump will only raise them up by a few pixels -- placing them back into a position where they can jump again. The character can become stuck in the ground like this fairly often when hitting the ball without jumping. The red orb can sometimes reach the top of the screen, making it extremely difficult to hit, too.
I love the XP screen that showed up after losing all lives, and I love the brick-breaker style of game. I never played breakout, but I played a few different versions of brick-breaker games. I love the fantasy style, and can't wait to see what this becomes!
(Also, played in 4k, and first thought I had to click on the orbs until I found the enter key. Sometimes the red orb cannot be clicked on, or doesn't respond to it at all.)
