Hello, sorry if the game is a bit cryptic, it was made for a school project under complicated conditions so there's really only one functional puzzle (the first one with the tiles in the first room).
For the time being, the scanner only serves to solve this puzzle. Each of the buttons gives an indication of the various objects to be found in the room in order to place them on the tiles (if you want the solution, please contact me privately at armoniadam15@gmail.com).
The other two rooms were modeled to have one puzzle each, the beginnings of which can still be seen (Morse code/fuses/pipes on the ceiling).
The various problems you've raised are known, but unfortunately can't be patched at the moment. Sorry for any inconvenience.
In any case, I'd like to thank you for taking the time to have a look (from Kraken) at our game and I invite you to test the others (I promise they're more or less finished xd)
