I just couldn't press the fullscreen button on the bottom right, F11 didn't help either because that just maximizes the browser. I don't know if the love point system was bugged because of that but I guess so since I can't find any other comments that had this issue. So basically the love point system just popped on screen after a restart of the level and I couldn't click any upgrade buttons or close the window which made the game unplayable because the window stayed on screen even during gameplay. This happened in the tutorial as well.

Thank you so much for taking the time to answer! We've increased the height of the web player for the game, the fullscreen button should be clickable now :)
We uploaded yesterday a new build that fixes some game breaking bugs related to the UI among other things, maybe the bug you had got fixed along the way? We would love to know if you give it another shot! :)
