Hey there! The snake is a character that will be part of the main plot across a future chapter of the game. For the second character you mentioned, his name is Brando, and we did have plans to add a scene where you can fuck him. It's just been on the backburner since we had to focus on other things. As for the bondage scene, you may be referring to Berac's scene in day 5. Berac will be replaced with a different character and that scene will be reworked in the near future. That said, there is still a bondage scene in the game which can happen on day 4 (one possible outcome of the Mindalu suite encounter) depending on your choices with her.
