Well even more than this - if you like these ideas I planned to make my own backrooms game in the future and have tons of (in my opinion) good ideas throughly written out. You guys have basically made your game (well - plan on) making your game into what my ideas were - so I thought I’d share mine with you instead!!
I thought it would be cool to have the lobby your irl house, and you enter the backrooms originally by noclipping accidentally. More on this another time if you are interested. Now the thing is that when you complete levels you not only fill out information in your journal based on what youve found in the level - but you unlock cosmetics based on the level in your house to show off to friends!!
An example would be a moist carpet when you beat level zero, or a bacteria lamp the first time you see bacteria. This gives it more replay ability as well as giving collectors something other than just achievements -plus you can show off too your friends :D
The journal unlocks as you view entrances to the level, exits, entities, etc, and fills out page by page to eventually make you a bada- an amazing explorer :D This in my opinion helps players map out what is hopefully eventually over 100 levels, as well as give you more to find in the game :)
Thank you for taking the time to read this! I have much more too written out if your interested, just dm or reply here! This includes more on the topic written above as well as several other fleshed out ideas for the best (again, imo) backrooms gameplay possible :)
