My ONLY complaint is that body upgrades get locked out in the end, also I'd like more crystals to max out. Also would be cool if there was shrinking and or growing and another NPC to compare with.
EDIT:! NEVER MIND I am le idiota, there is sandbox after you unlock All endings
Otherwise absolutely stellar. Also good on you for actually pulling off a long hair how it Would be in real life. Oh and longer longer hair upgrade would be awesome , but anyways.
