Oh I see, I don’t think I realized I could sprint to be honest, or did so subconsciously, my bad. If I could make a suggestion on that - the footsteps should be quicker when the player runs to signify that, as the speedboost itself isn’t that noticeable.
I tried to test monster despawning once when I played it - When I heard the noise and ran back to spawn without looking back, and it jumped me near the starting ladder. I assumed based on my previous runs that it jumpscares you when you look at it, and that's why I didn't look back, but that might have been just a coincidence then. My bad on not fully testing out my theory and good job on implementing it then.
I actually probably never gotten to know it despawns because I encountered it right after it spawned most times. And 15 seconds is surprising long to run around especially if you don't know if it will go away. Maybe it could do with an additional timer, which starts when the player sees it(unless that's already how it works), one that is shorter, that gets longer more times player encounters it?
I think once when I sat around trying to input the code it might have despawned. Because after hearing the noise of it spawning, I ran to the machine room. And I don't think I have encountered it then when I left. There is no sound cue or anything like that if it goes away is there? So I didn't know if it disappeared or failed to spawn in the first place, not sure if that’s worth adding or if that might detract from the tension however.
The idea of making the generator open the door would be cool, and would also add some variance to the environment with cables going to the door.
I’d love to play the game updated post jam, so keep up the good work.
