Hi!
I've made my father play the game.
Prior experiences: Played the first 2 chambers of portal and about 15 minutes of minecraft years ago and looking at the floor and being stuck on doors.
He played exactly like you described on the video. He even hold shift in the long part to run, so it was satisfying to see him playing.
I noticed only two bugs with the game
1 - In the door that changes the mouse movement from horizontal to vertical the collision box with the door is somewhat buggy. I had to help him and it was even tricky for me to pass that door. I think it was something only that happened in my situation. So I don't mind that much.
2 - The last part when you have to jump in the last bridge, my dad didn't jump but he still reached the bridge. I think the bridge is too near.
A few comments:In the same last part, my father used the left hand to sprint (Shift), and the right hand to move and interact (W and E) (He didn't jump as I mentioned), leaving the mouse without any hand.
I think it would be convenient to add some type of puzzle that requires the use use of both hands (one in the mouse and the other one in the keyboard).
I will try to make my mother to play. And email you afterwards.
Thanks a lot for making this minigame!
