You actually beat me at wall of texting, doesnt happen often. Yeah I actually went through a few lava streams already, can survive in there long enough with upgrades, perhaps even possible to stack two of them. And yep, somewhere in that thread you also see the planet, with a lot more teleport points than expected, so it seems quite bigger than the previous games. And now that you mentioned it with the spider/headcrab/facehugger, the animations where multiple enemies join in would be another plus point for me.
Going by that list of games, yep, seems like a platformer fetish heh. Actually think I played nearly all of them, and definitely heard of all of them. So you also discovered Kyrieu I see, the person behind Aster and Kurovadis and... other game I forgot (looked it up, Eroico). That would have been my first recommendation, since those games are english too. And actual game wise they are darn well made games, probably why he did non-adult versions too (at least I remember him saying that).
Just throwing a game out there that checks most of the the thing you like would be Parasite in City by Pixel Factory.
Is a platformer, shooting, kinda pixel style (even though more pixels I guess), destructible clothes if I remember correctly (thats the english term that has manifested) and definitely has some interspecies in there. Has more of a survival touch and some zombies but still worth it. And can be found right here on F95. Some downside though, in case you like it, there probably wont be any sequel, as the creator is from South Korea, and they just outright banned any pornography. Consume, produce, anything. And as someone making money from it he cant really circumvent it.
Can probably come up with more games soon, just one I remembered right off the bat. And I can kinda see why platformers work the best for you, since they are probably the most easy to use without a translation, that kinda makes sense right? Or is that also your favorite regular game genre?
And last, my favorite games/genres/anything? Uhh, tough question, since I play nearly everything. At least genres are no restrictions for me, only some quality would be good, but thats also subjective sometimes. Played hundreds of adult RPG's, platformers, strategy games, simulations, management, fighting games, even tower defence adult games. Most of it japanese though, but yeah, hoping for more from the western market. You mentioned Lewdest Labyrinth for example, love those dungeon crawler games.
Kinda generic answer, so more specific, I like those RPG's, for example running the character I control into situations it probably doesnt want to be in (good its just a character), and RPG's offer a lot of content for that, also they really cover every kind of fetish they want, just depends on the setting, so a lot to chose from. And fetish wise, I think im kinda blessed there, because theres only a few I would prefer not to have, and probably nothing that would make me turn off the game instantly. One of those I prefer not to have is Guro for example, dont see how unnecessary mutilation of a sexy character is useful, or even remove body parts... nope, leave those nice body parts where they belong, they might be fun to play with later!
And last, dont think you need to mention english not being your first language, its probably too good for some forums I know, but by coincident, its also not my first language. Alright wall of text over for now.
Edit: Oh one last thing, since I discovered that, did you put Explorer of the Golden Planet in higher resolution? Top left, you can click on that game Icon and hit 200% which makes the screen bigger. Still looks pretty nice.
