It's kinda unreal how creatively simple these are
Portal snake might be my fav. The only one I have issue with is darkness snake. As you get bigger, I think the cone of visibility for the snake head is a little too small for you to be able to make split-second decisions
It think it would be better if it gets a little bigger depending on the length of the snake ( Or it starts a little bigger and stays that way )
Immersive-sim snake when ?
Also, downloadable version when ?
