First off, congrats on your first godot game! I think there may have been a scaling issue with the game as I can't seem to do anything besides buy the one grey bacteria dude.

Thank you!! Was lots of fun and I learned a lot. I've put a ticket in jams server so I can release the fix and update the description a bit for how to put them to work. For now the solution I know for now, it is to zoom in or out the browser page until a room fills the game screen. And to be able to assign it to work you have to click on the bacteria and a menu with the tasks will appear.
