I found the game after coming across one of the animations through a twitter post and decided to try the demo here. The game was rather fun to go through for both the regular and all treasures ending, yet I seemed to have a problem where the Perfect Run scene would never show up. I collected all treasure, avoided all encounters, yet nothing. In fact the animation for the all treasures ending played instead but was bugged out and didn't show up.
Apart from all that, my only issues so far is that the game doesn't really mention E is how you interact with stuff. Leading to moments early on where I was unsure how to interact with levers or the exit door. All the while enemies can sometimes decide to wonder into spots making certain treasures impossible to snag without getting caught.
