It's definitely challenging but it's really fun and super satisfying when you actually make the shot! I love games with unique but simple mechanics and this is a really nice mix of side scrolling beat 'em up and basketball. At first I thought the attack had way too much start up, but once I got the hang of it it became really fun to time the punch to clock the skeletons! Great marriage of the two genres and even though I wasn't very good of it I had a blast!
