Hey thanks so much for playing. You're definitely right. I unfortunately had to rush a lot of elements to get the game done in time and I'm pretty fresh to gamedev. I really wanted the menus to be more immersive - I only had about 5 minutes before the deadline.
There are some updates in the WebGL build, if you played the download version it doesn't have indicators on the items for what button to press, and you can't jump on the moving platforms (but you can on the web build).
As for the ending, you have to return the computers once you have all 3 to the basement area and jump on that little platform to 'revive' your friend. But it totally wasn't clear at all.
All in all, I have a lot to learn and I really appreciate you taking the time to comment!
