Keep an eye on this one. Not much to see yet, but what is there shows promise, and the game's predecessor came out quite good. Combat impreg is a rare jewel and this game already has a little sample on offer. As of v.0.01 you can see all the H-content (namely the hugger monsters, which are a personal favorite type of enemy and especially fun in sidescrollers, along with a tentacle CG with very solid writing) in about three minutes including the opening, and there's nothing to really explore beyond that.
The combat doesn't feel like anything to write home about, but that's probably a WIP. I doubt it will change a ton by later releases but it feels serviceable, doesn't have that awkward fucking problem with hitting enemies that are very close to the floor that some sidescrollers have, and it has a basic combo system. The checkpoint(s, but there's only one I saw) seem like they'll serve for healing, travel, and possibly zone resetting, and there's a "souls" currency from killing things that has no spending purpose yet.
Also, have you ever heard of the word "vituperative" before? Me neither.
