Nice work! A few notes as I am learning how to play this:
- Could you put directions for how to move? It took me a while to figure out it was W/S + mouse motion.
- /restart didn’t work for me the times I’ve tried it. Somehow I’ve glitched few times and was frozen mid-air.
- It’s not obvious how to actually start the game. Maybe an arrow or sign just to get people going in the right direction? (I’m actually still trying to figure this out)
Sorry if these sound harsh! 
If you want to return the favor, I just put out a game and would love to hear what you think: Retro-futuristic tank game - SYNTH*BLAST
