Did you download the game from the browser of the itch.io app? Preferrebly use the browser, since the app can give misleading compatibility messages. Also, if you don't mind, you could play the game on a pc, since buying it gives your access to both versions.
Please leave more info on your problem so I can better help you (Android Ver, wether or not you can play other itch.io games on it, the complete error message, or anything you might consider relevant)
