finished the demo 6/10
a lot gorier than I expected. art was great. ~15-60 minutes of gameplay depending on how many times you die (game is punishing). sex scenes were alright compared to other side scrollers. one issue I do see is whenever you respawn, your ammo stays the same so if you keep dying you’ll end up with 0 bullets.
I don’t know what the creator was thinking while making this but was the gore an artistic approach to the genre or were they just trying to be edgy? guess well never know.
6/10
4/10 nut
