This game has a lot of potential, I'm not a fan of puzzle games, but the concept of using external things to pass through the doors is really fun, it got me! I liked each puzzle
I won't lie, I got a bit stuck in the graph room, because I did not know about the Desmos software. Maybe you should put a link to the website or something, just to make it clear
Other than that, you did a nice work! I wasn't expecting that ending haha
