Turbowarp: https://experiments.turbowarp.org/pointerlock/904986295 Click to shoot, arrow keys to move and WASD to strafe left and right. Use the mouse to look around, and E to see video options. Collect all the tech parts and find the exit door without being killed by the monsters. Have fun!
Huge thanks to Griffpatch for the 3D game tutorials. Maybe consider pressing love and favourite? I put a lot of work into this :) This is best played on turbowarp, link above. (Turbowarp locks the mouse in place, for a more immersive experience. Press the green flag and then the game screen to lock the mouse and start the game, and press 'ESC' to show the mouse again.)
