It's really quite precise with the timing for when you grab those boards, to the point of feeling luck-based at times. It didn't immediately click to me that the partially transparent hand meant I couldn't grab onto the board either, especially when you lose after one mistake.
Once you get a hang of the controls and timing, though, it's pretty darn fun! I love the character's swinging motions, and I found myself trying to beat my high score for a little while. Great take on the jam's theme!
