Strange, i can't find the problem
1. Please download the "SB // Orks Ryona BBC ~ Full Game [Uncensored]" archive
2. Unrar (using winrar or 7zip) it's contents, which should have 3 files (apk) and 1 folder (PC version)
Feel free to ask if the issue persists, or if there are any other problems
Cheers ;)
