I think that is impossible to complete, due to invisible "+" button.Would appreciate if you could check my game too!
the plus button is 100% visible. Please look in the top left and if your window size is not normal, please go in full screen
I messed with some of the settings as itch.io was cutting off part of it for certain window settings, but it should work now. Please try it again and update rating. I'll be sure to check out your game. Thanks
