Very pretty and sad game. The controls can be a challenge, but I'm pretty sure that's the intention, to make the player feel for the challenge that is the life of our protagonist, the Triachnid.
Also awesome to see an appearance of it in The Binding Of Isaac and its remake. Though there it's like, big. I wonder what its size really is compared to a human? Would totally love to hold Triachnid in my arms and pet it, poor little thing...
The music from the Tin Hat Trio is also phenomenal and a great, great choice that very much fits the atmosphere of the game and its world.
Apparently this also takes place in the same world as other games of yours like Cerebrus Peashy. Nice. I love connected worlds.
