I just bought another one, Squeakross by @LukaTheMouse, and this is why I still haven't finished Princess Farmer, Kitsune Tails, Quantum Witch, Blobun, any of the cool games made by Fedi people, I haven't even finished Improbable Island yet and I'm probably not gonna because the creator is a dick but anyway back to Squeakross, it's a nonogram game (like Mario's Picross) paired with a house-decorating doofer and first of all the game itself is a joy to play but secondly holy shit the coats of lacquer this guy's brushed onto this, like whoa, you can see your face in it. Polish upon polish upon polish.
It's a Windows game but the itch.io version runs fine on Steam at least on my computer, what you do is get the game as a zip file on itch, uncompress it somewhere so you get a .exe and some other stuff, you open Steam up, you go to Games at the top -> add a non-Steam game, hit Browse, point it at the .exe, then you gotta right-click on squeakross.exe in your games list, go to Properties, then Compatibility, tick "Force the use of a specific Steam Play compatibility tool" and tell it use Proton 9.0-4, and then you're done and it'll load and run just fine. It probably runs with other Proton version too, I didn't check.
@elfi thank you so much, I'm so glad to hear my little game helped others 😭 💛
