This looks like a bug where the moving gets kind of wonky; Same problem as alterhistorian, since I used the same framework to handle panning and zooming. ~~I'll disable it on mobile since, unlike alterhistorian, the game seems somewhat playable there~~
Edit: It actually isn't playable on mobile, some upgrades go offscreen after you unlock enough things. I will work on making the pan and zoom controls work on mobile which might fix alterhistorians' - When I do have the time of course
