For reference my download stats for last year's entry are currently:
RunawayRails_Android-Phone-Tablet.apk 24 (flatscreen only phone version)
RunawayRails_MetaQuest.apk 22
RunawayRails_Pico.apk 13
runawayrails_linux.zip 28
runawayrails_windows.zip 34
I didn't make a webxr version, godot's webxr is broken on pico.
