Hi, Jashin. I've been watching the game and I have a couple of ideas.
1. Monster (or boss). I drew a concept art on the theme of a mutant plant, 
. The arrows indicated the direction of movement. If this monster is a simple enemy, I suggest making a simpler version of the first boss, he has one hit on the floor and a rare tongue attack if the heroine is far away. If this monster is a boss, then it has 3 phases. In the first phase, the boss follows the heroine, swings and strikes with his tongue, knocking her down (to dodge, you need to sit down) and goes underground, appearing in front of the player blocking the way, in the second phase he walks around the corners of the arena, scattering stones that you need to dodge. in order to either move away or hit/shoot, in the third phase he runs from one end of the katra to the other (to dodge, you need to hide behind a stone, some of which will break the boss while running.
2. boss hp bar. I suggest adding a health bar for bosses.
3. A trap in the forest. A trap in the forest covered with grass on the ground, a trap similar to a trap with a spider in the wall. The heroine will not fall if she crawls without waking the monster. After you get free, the monster will slowly crawl after you, and you need to run away 2-3 times to choose the right path. If you are caught, you will be raped and thrown out of the pit.
4. the change of the heroine when infected, depending on the raping monster. The main character will change depending on the monster who raped the most times (the effects do not mix).At the second stage, the changes are minimal, and at the second stage they are already very noticeable. If the sperm monster raped the character, the character will turn white, white smudges will appear and a penis will grow (either sticking out from under the skirt, or in the form of a bulge under the skirt), if it is a fly, then wings appear, and hands become the paws of flies, if a rat is raped, then the chest appears, and the character begins to hunch, and so on next.
