I enjoyed the hints of a story here! I had a very satisfying "Ahah" moment when I noticed the first cracked open door.
I think I found four endings, with two variants of two of them, but I got stuck on a door branch that lead me to an endless expanse of road where I couldn't find anything to interract with.
It's a very cool concept, and I'm sad I couldn't figure out how to find all the endings, because I got the sense there was a deeper story that would be revealed once you'd seen every end.
I liked the use of scroll wheel to open the door! It made the choice of which door to open have more weight than a simple interact, and I loved that once one door was fully opened, the other shut completely. After my 3rd or 4th playthrough though, I was getting aggrivated at it. I think the scroll wheel control would feel more satisfying if the interact area was a bit larger, so I didn't have to adjust to follow the edge of the door to crack it open. I really did like the unconventional control, just needed a touch of finessing to feel good!
