@JenJen No worries! This is a judgment-free place! We want everyone to be able to enjoy our game, regardless if you're a pro gamer or not!
In level 1, I would recommend drawing leaves in a circular pattern around the top of the tree. You'll notice that when you finish drawing leaves, the ink gets pushed away. You can walk through the green patches of ground that the trees create without taking any damage!
If you're melting just by standing on normal ground where there's no ink or trees, that means you've encountered a bug and it's not your fault whatsoever!
