The grass is a bit confusing. I thought I have to stick to the road for seconds. As the direction changes every time, it's really hard for me. Do you want to make this shifting control the core of game?
The movement control feels good! And I enjoy the levels! Good job! I wonder why the tongue control was designed as one button shoot and another button withdraw. I was imaging a simpler version: short click (shoot & withdraw); click and hold (shoot & stick); release button (withdraw). Don't know if this would work better. Perhaps you already tested a similar solution.
