I love that I get to play as a bat, first of all. They are underrated critters. I tried playing using the graphics (I like the style, simple but has character) and with my eyes closed
I found that with eyes closed I could avoid the rocks and get a decent run going but I struggled to find the bugs. I agree with others saying that keyboard controls might be helpful, I'd even throw out a suggestion that you have a kind of lanes system. If you swapped between (say) 8 lanes it would be easy to announce and track your location and you would always know whether you are going to touch something or your 'beam' is just clipping the edge
I had fun with this one, the theme and the gameplay matched up really well too
