Here is a cool little demo I made a while ago, its my attempt at a 3d portal game. I saw CodeTycoon’s [awesome game](https://forum.makecode.com/t/portal-3d-on-makecode-devlog/40885) today and was inspired to post this. It has two levels, I made it in one day.

Controls:  
Arrow Keys - Move  
Z - Fire Blue Portal  
X - Fire Orange Portal  
C - Interact with cubes, pedestal buttons, and the portal gun display.

It has working cubes, buttons, a janky portal gun, and high energy pellets. I do not plan to continue this, but its a fun five minutes.

WOW this is FANTASTIC! The demo you released a long time ago was actually what inspired me to get started on my own engine! Great work!
