Nice stuff pretty well made, I made my own asset pack if you wish to try it I can send it for free for air hockey :) https://verzatiledev.itch.io/air-hockey Yes shameless of me to advertise it, but might fit just giving an idea if you are interested would help me as well see what I need to remake or do.
Awesome game its really smooth with AI I think maybe a few sound effects and its top notch!
