The game is deployed right here.
I recommend glancing at this write-up before playing to familiarize yourself with the controls. Also, because it is unclear: the objective you're looking for is a pure red-colored book. You'll know it when you see it.
This is a WebGL build of the game ESCape from Kemper that I created with a team of 4 others. The original repo for the game as a whole can be found here.
This repo is just for testing out how well the WebGL build can run. It is deployed on Github Pages right here. As is (and as you probably can see), the game is quite laggy and does not run well on a clean, untampered chrome browser. However, if you're using a computer with a decent graphics card you can enable hardware acceleration in the Chrome settings and the game will run much more smoothly such that it is playable. Go to Chrome Settings --> System --> "Use hardware acceleration when available."
Also, for more thorough information about the game, please visit the repo and website for the game (linked above). I hope you enjoy this spooky game if you try it. (The downloadable version that gives you the executable can be found on the website.
