Harem Hotel is a visual novel. It's not a fully rendered 3D game. I can't add more than still images to the vast majority of the game. Even the animations are just still images flashing on your screen at a high frame rate.
I'm not sure what you're referring to when you say "The games on your laptop". There are no games on a computer, and you don't interact with a laptop in Harem Hotel.
I would love add more dynamic sex scenes, which is something I tried to do with Freestyle. But I can't do much more than this because I'm just one person developing this whole game, and I'm limited by the engine I use, as well as trying to keep the filesize of this game small. If I added animations everywhere, this game would begin to bloat to easily double its current size.
