most of the ads are either temu or online gambling. are you really sure this game is safe? Also if you decide to close the game due to pop-up ads with no reward, they will increase your progress time. from 2 minutes moved back to 10

on some of the later maps the land zones are poorly done like icy Isle why can't i use the huge stone portion. I had some good ideas for the space but I can't even use it. its still a good game, i don't have to spend real money on to beat it.
