There's a bug where reloading the page can cause a worker to become disassociated with an upgrade, and can be assigned to upgrade something else. This makes it incredibly easy to start plenty of upgrades without having to pay Shiny for multiple workers. Could you fix it?
Two problems: First, going into a wall acts as a no-op, even if that would kill you. Second, there's nowhere you can click in the game that doesn't cause some sort of change... which means if you alt-tab away, you can't put the focus back in the game without breaking something.
The game occasionaly 'crashes' - changing mode does nothing, clicking on the map button does nothing, clicking options loads up the options pane but clicking those buttons does nothing. Trying to figure out why.
