This looks like such an amazing game. I've only just started but wanted to say a couple things.
The lightning gems are terrifying at the beginning. I have no idea what triggers them or when they appear, unless I get hurt or die. They're so fast it's crazy.
I also clipped through the grass of my island and had to restart. I was just walking and it may have been a lightning gem or a small invisible hole.
I'm excited to see what you do with this. I love it so far, even if it's a little rough.
