Looks promising. Needs some work on optimization though. This tool came in really handy for me in my project. After you download the Metrics Tool there is an APK hidden in a sub folder you can side load to the Quest. It will help you figure out places that are running well and places that are not. It will also show you if its CPU limiting or GPU.. or memory but I don't think memory is much of an issue in your project. I am a Unity developer so I do not have much experience with UE but am more than happy to share the steps I took to get the quality and performance I achieved in my project. If you do decide to check it out note that I designed it with a Quest 2 and it runs well on that (most always at 72 fps) but as I am pushing the Quest 2 to its limits the Quest 1 does not like it to much ( 40's fps) XD
