- Which version have you installed? More variants available here: https://github.com/yancharkin/SpelunkyClassicHD/releases/tag/1.2.0 Try yyc build.
- Have you tried the HTML5 version (it was available among the old builds)?
- Is there any kind of error message? If there isn’t one, the only way to get useful info is to connect your device to a computer and run ADB. Can you do that?
