Can you recommend any similar games to this one? I just want to play something similar.
Aishteru (made by lxust_r_o_s_e) is another one. It's inspired by Captivity (with some references to it) and has very good scenes that are on par, if not better, than this game. However, it has far less content, only having a single stage, because it was canceled.
The NSFW stuff in the game is locked. To unlock it, follow the instructions in the comments of the Aishteru Itch page.
Condemed (made by Dos Arracachas) is another one. It's still in development, to my knowledge, and you can also find it on Itch.
