of course a cirno game would have this happen 😅 it works on my computer, so this kind of issue is mostly likely 1. it didnt download correctly, just try downloading again to see if that works, 2. your antivirus snagged pieces of code from the game and wont allow it to run, in which case turning it off should allow the game to work (or redownloading it with it off, one of those lol), and/or 3. youre missing a driver on your computer, but this is the least likely and i suggest the others first. hope it works next time you try!
