Nice game, really chill! The web build worked for me, could go to the end credits without encountering any game breaking bug.
Good looking game, nice mechanics, a bit long on the beginning to get the first upgrades, and then a bit long waiting for 0² to deplete, would have been nice to have an "end exepedition" button of some kind. But overall a good experience!
Couldn't climb the credits up to the top though ^_^'
