Web builds should be fine-- the majority of the issues with WebGL stem from WebGL not liking variable loops or implicit casting. I used the burning text effect on my web build of Mint Condition over here: https://makevisualnovels.itch.io/mint-condition
I don't have specific issue reports from Android builds. If you run into any issues with an Android build, feel free to reply here or find me in Discord and show me the error and I should be able to resolve it. I'd be surprised if they run into significant performance issues on Android, but there are likely some optimizations I could do for the platform or alternative methods I could recommend failing that.
