I know, right?! The game is inspired by an existing board game I know from my nephew that is called "Roadblock". I created levels by myself, but especially the hard ones I "borrowed" from this board game :) Thus, I "just" needed to create the specific building blocks to create a level and rebuild these ones eventually :D
I am sorry to hear that it did not work out of a sudden! I don't know what happened here, as I never experienced this issue...what browser were you using?
Thank you so much! :)
