WHAT A GAME!!
Absolutely don't let the drawing put you off!! Not only will you miss one of the best AVN storywise, but I guarantee you that as the story progress you will like it.
The design of the monsters are very well done, they appear very aliens and original, a far cry from the monsters you can see in western horrors. Even the humans characters, have a uniqueness that make them attractive.
Talking about characters, one of the strength of this game. Each of them have their own story and personality, they are flawed and well constructed. You know a character is well-built when the author makes you love them, then hate them, and love them once again. I'll let you discover that for yourself
Story. The greatest strength of this game. You play a 18 years old boy with a troubled past who suddenly gain shapeshifting ability after an encounter with one of those monsters whose origin and intention are unknown.
From this introduction, a great story unroll. Who are those monsters? What do they want? Where do they come from? What do you want to do with your power? Who is this organization that claim to want to save humanity? What does Ella scheming? Such simple questions are intertwined within a great story-telling that will make you lose some sleep as you keep unrolling and make you crave for more.
Because yes, the game is LONG, there is a shit ton of content storywise, you are looking playing for days, depending on how you play.
For porn, it's good. You will have vanilla as well as more spicy stuff like NTR, trap, futa ect... (ALL OPTIONAL btw, the trap characters can be turned into a female if you chose the option for it), and weird, for the most edgy of us (meaning monster fucking, brain fucking through the ear, tentacle porn, gender bender where you can turn the MC into a slut, rape, and one necrophiliac scene, again, all OPTIONAL).
TLDR; If you like dark fantasy with lovecraftians elements and superb storytelling and really good fight.
PLAY.THIS.GAME.
Even if you're not a fan of horror, just play.
And if you love this, consider donating to his patreon, that's actually one of those game that truly deserves it.
Have fun!!
