Still fondly remembering Shufflepuck Café from my earliest childhood, this captures the aesthetics really well i think. Theres already a lot of polish for the little content it has.
Now im pretty bad at this game, but i can see it being really fun in a chill way once theres more meat to it and some rough edges are ironed out, which is mostly usability stuff.
The billboard sprite numbers when counting the points are not really visible in the little top right viewport. At the same time, the point counting can drag on for a bit, especially when theres like 5 pucks on the field and most aren't moving. Watching each one be counted gives the player pretty much no new information and takes a long time. Maybe let the player press a key to speed it up or add an option to tell the game how fast its supposed to be.
Options in general are needed, both for display settings as well as for the audio. Control binding maybe too, which might be easy since its just a few ones right now. Even if theres no rebinding, there should be some prompts at first to let the player know what to press. Arrow keys for positioning/turning is intuitive enough, but i smashed my space bar before realizing i had to use enter for shooting.
Pretty sure you are already aware of most if not all of these things, but here you have it in written form by someone else. Keep deving and make a great Shufflepuck successor, my nostalgia demands it!
