There's a bug where the danger/lose zones don't go to the edges of the screen and you can build next to them. Later when I completed the height they expanded and covered my buildings so I lost.
Thanks for letting me know! Others have also reported this. I've quadrupled the size of the failure zones, so this should be fixed :) They should be big enough now, unless somebody reaches even more ridiculous heights. Y'all are getting much higher than I ever did during playtesting!
