It is indeed my first 3D game ever. I literally had no knowledge on how to do anything 3D related when I started, so the month or so that it took to put it all together was a real struggle. Especially since I'm not really much of a coding person.
But I liked the challenge and it allowed me to develop my skills a lot. I learned a ton about 3D modeling, coding in general and how to implement "stuff." Well, at least how to do all that in Godot.
The dungeon is very bare bones mainly because I ran out of time to decorate it. I was already struggling a lot and the level design kind of ended up taking the back seat. I had plenty of ideas, very little time to implement any of them.
I'm glad you noticed the Drakes behaving slightly differently from one another. The green Drakes are pretty shy. They like to hang back and just observe more than attack while the red Drakes mainly just advance to pummel your face in.
There isn't a gallery per say. Though I had one in mind. You would unlock it once you beat the game. Have some still shots with the drakes being all kinds of naughty with one another and the player and view all the animations they have. But you DO get something.
If you find the "not so hidden" hidden pedestal and go through its dialogue, you'll unlock the EXTRAS menu where you can view all the sex scenes with the Drakes and the Boss Dragon. Provided of course you haven't gotten sick of them by the time you beat the game and get past the credits sequence.
