Uhm, I think we may be out of luck. Anyway, only do this in a sandbox if you insist. One wrong click and all your saved passwords could be with the hacker, plus who knows what else. So... don't.
Anyway, the game is still there. Just delete the main game EXE straight away. You don't need it to launch the game — it's the infected file, and it also launches the actual game.
After that, you can try going deeper through the folders. There's another EXE there which I didn't properly check, but it seemed clean. You can launch the game through that, but again, I didn't properly check it, so don't take my word for it being safe.
The actual game appears to be all there in the download.
Of course I could share a cleaned-up version, but then how would you know I didn't put my own virus in it? lol.
If you're going to risk it, delete the top-level EXE as soon as you download it. There were also a few other folders I deleted while examining it — I don't remember exactly which ones at the moment. They contained code related to the malware, although they weren't themselves executables.
Basically: if Windows asks to install something, make system changes, or requests unexpected permissions, cancel it. The actual game can be launched without making system changes. Any unexpected permission popup = No. And make sure your antivirus is updated before trying any of this.
