Thanks for your feedback, MG! This game is based on the hallway sections in FNAF SL, so all mechanics and jumpscares are intentional. Mark is based on the smiley thing in Roblox Grace.
Sounds: The amount of sounds and their volumes are definitely overwhelming and I can tweak something such as the timer's volume low, but other than that it just adds to the difficulty.
Flashes: The audio tells you to flash so that you don't run into anyone or vice versa, but that's a total lie. Instead I've made a hidden countdown which when turns 0, ends your game. So the player is forced to flash constantly, otherwise you'd just win without flashing even once. The reason for lying in the audio is to not tell about this mechanic.
Creatures: I can add descriptions to them if you'd prefer, but I thought that players can figure it on their own via repetitive playthrough attempts (or by understanding the instructions audio).
Controls: I did had keyboard controls for the game but removed them at the last second.
I will attempt hard mode a few times and tone down its difficulty if I couldn't win. Let me know if you need any gameplay tips too. Good luck!
Edit: replaced "you can just win" with "you'd just win"
