Thank you! Unfortunately I can't pinpoint the exact problem as I'm not an Android expert and with so many devices out there it makes it even more of a challenge. File size wise this game is pushing the limits of what the game engine allows for Android systems, that could possibly cause issues/lag/crashes. It absolutely works though, plenty of Android players around and I also tested the game thourougly on my own mid device.
In the coming version the game will be split into two parts for Android systems though t that will take a while. In the meantime maybe Joiplay could be a solution.
