Here's some feedback if you want it:
the upward swing tends to drag along the floor so it would be nice if the fulcrum was raised when you do that move, or if the angle was more diagonal. Any time I swing in that direction, I intend to hit something ahead of me and not the floor.
I never figured out how to control my swings, but the physics are brilliant so I think you have some leeway when it comes to unusual controls. It's easier than playing toribash at least. For the record I never played mount and blade or mordhau
Hitting the balls was great fun. I think some gentle auto aim would make it even better. Add a batting cage if you don't have one already.
I didn't like how the bat is always dead centre because it blocks my view.
The premise is fine for a tech demo, but I think being directed to rack up property damage is at odds with the very personal and anarchic feeling of smashing something with a baseball bat in first person. Knowing that I'm doing what I'm told is robbing me of the joy of destruction.
I want to see my robot's ordinary life and get a taste of his frustration, so that when he snaps, I can feel his catharsis. I want to target bullies and their cronies and until the other cogs in robot society come down to bring me to heel and I realise I'm the bad guy Falling Down 1993
