Game design is pretty quirky with the restriction of looking up and down, and I seemed to have some aspect ratio/scaling issues with the UI on both webGL and pc versions. I do like the dual hand controls but a nice feature would be the ability to 'peek' up and down. The game does build tension about why you're closing the door. With some sfx and appropriate music it would create a lot of atmosphere.

Good start and could easily build and play again.  I found the controls to be difficult and screen size too big for my laptop, but that's my problem, not yours.  I kept waiting for sound or even some background music.  I also thought maybe something was going to come through the door, adding a little fear to the game.  Might go that route.  Great job!

Really enjoyed the core idea here - anxiously trying to put the pieces together as the timer counts upwards. Quite different to be trying to close a door, normally in games you find yourself trying to open them.
