I think it is overall a good idea that will make balance easier and have each pick affect the gameplay in comparable degree.
The creatures could mostly be reduced into what used to be a categories all their own, this time each subverting different part of gameplay:

-An aquatic (merfolk?) with perpetual dolphin's grace and conduit power but permanent slowness III for which DG compensates in water (and that's good with how absurdly fast it gets with depth strider) but makes you ungainly crawler on land. Lack of water won't kill you, but inability to dodge projectiles or escape melee attackers will be a challenge. Forgoes traditional traveling;

-A forest fae capable of brief flight, going invisible when sneaking, and fast movement, especially on leaves or wart blocks, but frail and greatly slowed down by armour. Forgoes traditional combat from damage-avoidance perspective;

-A cave dweller (dwarf? troll?) that sees in darkness, digs quickly and is durable, but feels unwell in bright light or open space and is ungainly with weapons. Note: burning in sunlight while overly punishing early-game, is non-issue with good stockpile of fire resistance potions. Forgoes traditional light-dark relation;

-A sapivore - combining very powerful alluring song and limiting eternal hunger that ties it to some NPC society. Forgoes traditional mob economy;

-A magician (elf? daemon?) having ability to create a variety of wands for casting fireballs, blinding enemies and such, but at cost of inability to melee and reduced hitpoints. Forgoes traditional combat from damage-dealing perspective;

Not really. I mostly work on this stuff as a hobby, so I do more or less as my interests change. Right now I am still nailing the core of what it's supposed to be

Become Creatures Lite. That's a nice idea

Yeah i just found it a bit funny :)

That's probably true. Even still, I wanted to give credit where credit was due
