A solid start, a few small notes/suggestions:
- Pacing of sex cutscenes feels a bit slow to my tastes, with little to do except wait or skip the entire thing. Could perhaps have a fast-forward button, a skip-ahead, or perhaps loops that keep going until advanced? Might change presentation though.
- Limited ammo, with shots needed for puzzles, means it seems possible to softlock yourself by emptying the mag. Perhaps the gun should auto-recharge slowly up to 5 shots or so?
- Lighting in air vents makes it rather difficult to see side passages, outside relying on flashlight reflections. Maybe some light sources, or a self-lit floor decoration, might help indicate them more easily.
- Pressing ctrl+tab to open status window while crouching plays the status window SFX but doesn't seem to show anything visible.
- It's possible to backtrack to the "sex" room with the gun and aim/shoot through the window, to no effect. Perhaps the sleeper model should despawn, or perhaps better some visual effect indicating the shot being absorbed by the glass window.
