Very interesting idea and definitely fun once I figured out what to do! I didn't understand that my mouse positioned the camera on my first play through. When my mouse pointer disappeared, I panicked and hit ESC, which made it impossible to move the camera and play the game. I read the comments here, and that helped me understand what was happening.

Just some feedback, that you're welcome to ignore :), the echo location only seemed to work when pretty close to the bugs, so I had no idea where to look until I was practically on top of them. At which point, I'd find them almost accidentally. It would be nice if the sound effect was mostly always present so that I could use it to guide me the whole time to find the next bug. Though, take this with a grain of salt, because you're the game designer and this is your game.

I love the idea for the game.  It just took me a while to realise how to use it maybe could of been a little clearer?

However I loved the originality of it and also the sound effects.  Cool game !

Nice game. I was a little confused at first because i expected to see a ship with bugs coming at it but I like the way you did it. You may want the time you get for finding a bug to be less. I quit the game after I had 100 points and over 300 seconds to find another bug. Nonetheless, it was pretty fun.

It is a nice idea to use only sound to find the bugs, but you kind of get tired of it pretty soon. I would suggest adding more kind of elements, like moving bugs or false alarms, to make the gameplay more diverse.

Also, be careful with the 2 color theme, when you are getting close to a bug there are some gray colors on screen.

WebGL version not playable for me - Screen too small (scroll bars in the HTML5 window - small within the page). Intro text is cut off in standalone and in HTML5. Some UI slightly cut off in standalone too. (1920x1080)

Interesting idea and a bit of fun.  I like the 'magnifying glass' idea!

It did quickly get to a point where I could not find any more bugs though and I ended up just moving the mouse around aimlessly waiting for some form of feedback. Could do with some form of on screen feedback when you are moving (eg. at least on the edge of the 'play area'?)
