Waited 2 minutes only for the game to just crash, Samsung J4, my disapointment cannot be comprehended as I am surprised on how the fuck can a 2D animation fucking crash and require a fuck ton of my cpu power, honestly how the fuck can you even do that shit, just fucking go with Godot, much better than money and cpu power gobling "Unity".
Based on comments, the issue is in all Samsung devices and certain redmi phones, which is weird how can your game which is quite simple that I can make it in like 48 hours, cannot be run in Samsung, like never have I seen such issue in a unity game, something is wrong and definantly in your part.("a performance issue in few mobile devices" literally two massive phone devices i dont think thats its "few")
