The current version seems very stable on Windows 10. The only thing ingame I noticed was that the sigh that plays when resetting the cup sometimes plays twice at once. Another notable oddity is that the game seems to use a lot of your CPU/GPU if it can. The game never ran poorly but managed to take 50% usage of both an i-7 7700 (4.8ghz) as well as an RTX 3070ti. Doesn't impact the gameplay at all but seems strange given the game can also run on a much weaker PC I tested with similar usage of ~50%.

Lol, I had to check this and you're right. I was getting over 1,200 fps. It was using 100% of my 3070ti and 10-20% of my 5800x... If you want you can go into the Nvidia control panel -> Manage 3D settings -> 'add' cowtastic cafe -> change max frame rate to your refresh rate, or 60, or whatever you like. :)
