Sorry about being unclear. I mean the game I'm making. I'm an app developer for a hospital, testing an educational application mostly consisting of animations. I've removed everything from the game other than the first few seconds of the animation and it still doesn't run smoothly on tablets. You can find it here : https://anaeht.itch.io/thalamus
I was mostly looking to see if there is anything specific I need to pay attention to if the app doesn't run smoothly on mobile devices but working fine on desktop.
