Woops, didn't see you had a topic about this before posting on your profile.
Overall I think it's a really cool concept, and I actually plan on playing through the rest of the game. The music, effects and overall presentation make it really enjoyable.
This is my critique if I had to write any after playing for a few minutes:
I'm wondering if showing the white arrow every swipe is necessary? The red arrow is understandable, but the constant white arrow popup might actually be distracting from the gameplay. Just a theory.
Swipe detection seems to be really sensitive. Maybe adding a buffer zone of a few pixels from the touch point before registering a swipe? I have a pretty large screensize so it's not really a problem for me, but on smaller screens, you might get some unintended swipes.
Finally, I have to ask.. why beetles?
