I like playing a 3D platformer from time-to-time. :) Made me want to do Minecraft parkour.
“Shift to Sprint” isn’t mentionned in the control on the game’s main page, but I can’t imagine myself playing without it : maybe add it.
For some reason, the WebGL build won’t fullscreen properly : as in, the viewport size stays the same.
Also please turn down the “thud” sound (I believe it was the door closing?), it jump-scared me a little. :(
Good job!
