Thanks for the feedback! Believe it or not, turning while charging did cross my mind a few times, so might be worth exploring that along with the other things listed.
I also found myself using the same three actions + the uppercut(Duck -> Swing) since that keeps enemies in the air for longer, and lets me charge up my bat at the end of a combo, but future enemy types will motivate the use of the hop stance as well.
I will be looking to commission for music as well. Figured since this was an early build I'd just focus on getting sound effects in at the very least.
