DISCLAIMER: I'm trapped in the cave, I don't know whether that's where the game ends?
I love the graphics and the music. They're both very authentic, and the latter is very catchy. However, if I may, the fact that there's only one, albeit very good, ground and wall style of tile, is noticeable over time.
The gameplay is amazing. The idea of swapping between various shells with different abilities, each with their own HP points, is very organic and fun, and fits the hermit crab theme. The controls always feel responsive, and if you die it's your own fault.
There's even a little, extraordinarily relatable, story to follow. Some of the funniest, cleverest stuff I've ever read concerning the woes of creative degrees, and man's individual struggle against capital. Oh, woe befall those who pursue the arts.
Amazing job all around
