SKIP TO 7:45!
Thank you for covering our game! The controls scheme follows the same direction as P.T. - Silent Hill game, where you HOLD RMB for a few seconds before interacting, it's not instant.
We updated the game recently, adding a little tutorial for the interaction control scheme and increased the size and height of the Hobo Alley Key, following player feedback. We also added a crosshair when zooming/interacting to let you (the player) know exactly where you are aiming.
If you ever feel like playing this new updated version, there is a second secret ending that you ALMOST achieved, but couldn't because you didn't hold RMB long enough. Hope you enjoyed playing!
