Look a bit above the comment section, right atop "more information" and read what is written there.
If you want to play on the phone, use the Maldives player app; it's almost the same as joiplay but can actually run the game without much trouble. Joiplay doesn't read our animation spritesheets properly, and that breaks most of the animations down. It can be solved by some adjustments in the joiplay settings, but I don't know the exact details because I don't use it.
And I am not trying to be rude on purpose. I just don't know what to say when the answers to a question are written right above the question.
