It's free so why not? Every race has a futa variant, they all have the same animations that males do but they don't have balls so if that's a big deal you're gonna be disappointed. I'm indifferent to futa but apparently this is a deal breaker for some? Right now the animations are a bit thin, many pairings aren't supported for certain animations and what few animations we do have are pretty basic. If you like futas and fat asses this game will give you a heart attack though.
Elaborating a bit more on this:
This game has currently 16 different species of catchable Nephelym (Furrys/Animal ear humans).
There are male, female and futa (without balls) variants of the nephelym. However, only 5 out of 16 species have male versions, because Dere (the Dev) is (self-proclaimed) pretty bad at making male characters, so he doesn't want to make males anymore and he removed most male variants from the game. The futas are basically the female version, with a dick model slapped onto their crotch (and it often stands out from the rest of the body, since it's just an extra-model stuck inside the female model).
The futas mainly exist so every species can breed within their own species (because there is no male counterpart) and just for the futa fetish (although Dere hates balls, which is why futas don't have balls).
Also, 3 of the 16 species have an "exotic" variant for their females, which means instead of just being human girls with fox/wolf/dragon parts they're full on furry/scaly. All others are just humans of different size with different body attachments.
On top of that there are 14 Hybrid species that can be bred from breeding different species combinations (e.g. Harpy + Dragon = Basilisk or Demon + Vulwarg [Wolf] = Hellhound)
