Use WASD to move around and the arrow keys to change your viewing angle. you can also adjust the FOV and RESOLUTION. HOLD '1' to see yourself and the entity on the map. The dino (entity) is visible through walls [bug], I'll fix it when I can.
This was a very TRICKY project to do. not hard, just tricky and confusing (a little bit) took me roughly 7 hours to make, and the outcome of a lot of try and error. I took a bit of help from the internet and youtube. however, did the most part myself.
