This was fun! I wasn't sure when it was meant to end, or if it would continue on forever, so I just clicked a red one early. One annoyance I had was being able to drag some windows but not others.

oh Hi Fanny! :D Yeah this game was made for a work game-jam I hosted. Theme as "Everything is a button". Didn't had time to fix not all windows being drag-able. It was intended to be drag-able. Wanted to make it so if you had 5 or more 'good' windows, you'd loose, but I had another jam to participate in :D
