Needs Work...
The sound of the Sonar is really not amusing to the ears. The idea of the game is very original though, I honestly can't believe that someone would think out of the box that far. But to improve this, I recommend making the hit areas of objects extend out more, because with the moving objects, this game becomes a hide and seek of geometric points, maybe try collision masking. Otherwise, great concept and mode of conveyance, the music fits well and the graphics blend nicely. If you make a sequel, and just tweak the collision masking (and maybe the buttons for level selection) you might seriously have a shot at a daily feature. Glad to have played this, favorited it.
