Really original idea and well executed as well. Kind of a peaceful game. As said below, I like the idea of scoping carefully and executing the chosen scope well. You even added the rays of light which is a really nice touch. Good concept, good game!
A few small ideas:
- Change shaking to alternating left and right, I think that feels more natural
- Implement some sort of goals to work towards
- Make the punishment of catching bugs more severe
