Just tried this game and I have a few things to say. First off, I love it! It's quite hot, especially certain endings. Buuut it does have some downsides.
I should note, I am not trying to be harsh here, this is my honest critique from my experience. It's a good game, and it has the potential to be amazing, it just needs a bit of work to make certain parts more fun.
1: Currently, there's not much variety with the enemy types in terms of animations. Don't get me wrong, the fact that they ALL have animations specific to them is a big plus over a good few other games of this "genre" I've tried. But at the core, a good majority of the enemy animations (including some bosses) simply amount to "get dicked".
Not inherently a bad thing given personal preferences for who to get dicked by. However, it does become a problem when there are SOME enemies with unique animations, especially ones that are rather "in-depth". For example, the dog enemy in the markets has a full multi-scene "ending" involving multiple fetishes. As another example the crystal enemy in the mines is completely unique as an ending (even amongst other games I've played, it's a very rare ending). But that is two enemies with more in-depth animations, all the others are variations of "get fucked", with one or two involving going inside the monster in question. I'm hoping that this is simply a "TBD" thing, and that more monsters will get their own unique extra scenes.
2: The bossfights, past the first two or three, become absolutely tedious. Now, I'm not sure if this is simply me having missed powerups or items or what - especially as I wasn't really going for the powerups, a good majority of them were in places I didn't have a clue to get to and figured there'd be a double jump or something later to facilitate getting to them - but at some point I found progression into the next boss to be completely and totally tedious. The boss fights did up in difficulty, yes, but even when you figure out the mechanics and are near-perfect in dodging them, you're still looking at a boss fight that's going to take the better part of five minutes or more to complete, simply because they have so much health.
High-hp bosses isn't inherently a bad thing but when the attack patterns have so little variety, it just becomes a rinse repeat that quickly becomes boring. Especially as there's no checkpoints in the fight, so if you have the boss at half or less, and fail, you have to restart that minutes-long boss fight from the start. For some bosses in particular - like the Witch - this led to me simply giving up, because the fight was either taking way too long, or had so many mechanics that I couldn't possibly figure out how to beat it without cheating (and even then you get stunlocked because of the stagger mechanic and the inability to use debug commands a good bit after taking damage, making the boss fight take even longer). For the Witch in particular I figured I was missing an ability, which leads me into the next point...
3: The platforming in some areas is too difficult. I'm not sure what the difficulty of the game is supposed to be, but generally I would think games involving pornography are not supposed to be a slog. The platforming in this one is proving me a bit wrong. Now, don't get me wrong, platforming is meant to up in difficulty as you go along. BUT the difficulty in this game ramps up a bit too quickly, in my opinion. Going from the simple jumps in the first area to multiple stories in the second that almost immediately introduces long jumps, head-hitting jumps and other such jumps from the second room. By the third area it was numerous long, difficult jumps WHILE enemies are shooting at you or otherwise blocking the jump! I basically gave up come the fourth area because it was too difficult. At that point, when I gave up, there were enemies basically everywhere and falling at any point was basically guaranteed death - and not even the fun kind of death, no, the boring tedious death where you simply have to wait to die because there's no way to reset (can't f12 to rush to defeat because of taking damage not allowing debug).
After giving up I figured I'd rush to the other areas using the teleportation feature, and I went to the very end of the fourth area, only to find... Enemies. Literally. Everywhere. I'm sincerely hoping that's simply a "congratulations on getting through this but there's nothing past this point" thing (I did get through it, painfully, to find the "end of dev" sign) because having that in the final product is honestly ridiculous.
TL;DR
The bosses are a bit too tedious due to their hp being way too high, the platforming is frustrating at a certain point, and there needs to be a bit more variety in enemy animations.
