If Dark Souls was a Metroidvania, then it would be just like Demon's Sperm.
This game is heavily inspired by Fromsoftware's "Demon Souls". You can definitely see the inspiration in-game. Honestly, the gameplay is very solid. Engaging fights, the controls are a bit awkward but not horrible. The game has different type of weapons, each made for a different playstyle.
Now, the cons: The h-scenes. The scenes aren't bad, but they're not good enough for a wank. They feel "dated" and while I'm pretty sure they were done this way intentionally, I just couldn't.
Overall, if you are a fan of the souls franchise and want to play it in Metroidvania, then you will probably enjoy this game. Otherwise, easy skip.
4/5 - I am a Souls fan.
