Attached is a picture of my game. As you can see, it is very simple, and is only using the same texture/sprite over and over again.

All of the "tiles" have their tick events disabled until they are needed. On my computer, it is a 70 fps, but on my phone it is a 6 fps.

I previously had this game in only UI, but now its actual PaperSprites, but its still getting immense lag.

I'm looking at these other more complicated games that have shaders, materials, lighting builds, complex maps, static and dynamic meshes, and a bunch of other things with huge overheads, then I'm looking at my game and I'm baffled that mine has such low framerates and theirs don't. When I look up how to optimize the mobile game, none of them apply to me because I don't use any of these things.

What could possibly be the issue here? Any ideas?
