The concept is nice, the 2D enemies in a 3D plain is interesting and reminds me of Doom... also why didn't they just make this on Doom. Everything after that feels very unpolished while lots of the animations are very short, some animations even look very scuffed. The MC is nearly T-posing in at least three of the scenes shown in the trailer so I have to assume there might be others like this. Asking for nearly $20 despite delivering a ham-fisted game is insulting, especially since way more polished titles are out there for not even half of that. Nah bro you don't get to charge extra for covering a niche fetish.
Also looking at the trailer, there seems to be no proper blowjob scenes at all... but the giantess enemies will still suck on the MC. That's some freaking bullshit right there, an oral fixation game with no sucking of dick.
