I like the new logo. Other have said it better, but it's a bit too detailed and busy to work as an icon. It also conflicts slightly with the current art style, being more saturated and cartoony than most of the game's current art/textures/models. It actually feels a little more blocky than the game itself, though the original icon wasn't block at all so it does fit better in that regard. I'm not opposed to an art style shift, especially in an early-access game, so long as everything remains coherent.
