This is fantastic. Love how much atmosphere you achieved with so little and the idea of a game gaslighting you with its own mechanics is fantastic - I'd love to see more. Unbelievable that this was made in Construct 3, too. Do you have any dev diary type content? Or would you perhaps be willing to share the project file so I could have a nosey around?
Small bit of feedback. There's a typo at one point where the pager tells you that the level is a test of your 'patients' - believe this should be 'patience'.
If you're ever looking for a composer to put together some spooky retro ambience soundtrack, I'd love to pitch in. Let me know!
