This is awesome feedback, really appreciate you taking the time to give it a chance!
Re-doing the swing physics has been pretty consistent feedback the last few versions and I think that will be my primary focus as of now coming out of the jam.
Most of the music in the game is definitely placeholder and I'll likely replace once I have a better idea of how much I'd like to spend on licensing. For now, I'm just using some of my favorite tracks that atmospherically match the vibe I'm going for. This is very much in transition from a hobby made fan game to a more "real" game and there's a lot of that still heldover for sure.
Thank you again for the feedback!
