The movement felt great, and the tutorial is highliy appriciated.The idea of matching weapon frequency to enemies is interesting. I think in need some more development, as I personally found it hard to match the tones just by hear, so I had to scroll over all the tones and strafe around the enemy while doing that. It was very close to something that could work for sure

I  prefer noob mode as I'm tone deaf >;

• I like it! I'm definitely not good at identifying sounds like this. Could be that the sounds between the enemy and the gun should be closer in style.
• Very stable game save for one bug I encountered where I died at the same time as winning and it puts me in an endless loop unless I refresh the website.
• Tried both regular and noob mode. Probably would be better to just have noob mode on without scope. Was unclear how it worked when I did the regular mode first.
• I certainly encourage you to explore the frequency-based combat. Maybe involve pickups or the environment.

Not bad. solid FPS controls and atmosphere. figting could be a bit more exiting though - all I ded was scroll though all frequencies until found one that does damage. there could've been some penalty for doing that but I'm not complaining too much :)
