The puzzles are quite hard but well made!
The style is good and consistent throughout, look quite nice!
the music fits it well, and although seems to loop a lot it didn't get annoying while I played it
One thing that I wish I saw in there was that if I tap up, then the character should keep aiming the bat up until another key is pressed. Instead of only aiming up when holding up. Would make those jumping up hits less tedious.
the feel of hitting the balls with the bat is quite nice. thought!
Over all, quite the nice game!
