I really want to like the game. It's probably compatible with hundreds of controllers. However, it's extremely difficult to understand what's going on. There's an awful lot of HUD content, and I can barely make sense of it.

So, I played it some more, and I realized (after way too long) that this game is really like a cross between Odama and billiards, which is quite charming.
The game doesn't have any code that interferes with controller layouts, so it's actually more controller-flexible than other Itch games that use Xbox plug-and-play too broadly. I'm happy to buy the demo.
