This is the best game I have played today.
I like the main mechanic of collecting good bugs and shooting the bad ones. The "How to play" button could have been more obvious. I completely missed it the first time I played and hade no idea what to do.
Also, the game got very difficult very fast, but maybe that's just me being bad at it. The only thing that bugged me was the colour of the bugs.
I know all redish bugs make bad bugs and all greenish bugs make good bugs. But how about that:
1. light green bugs remove progress of the red bar (light red bugs the opposite)
2. dark green bugs make the green bar higher and the red lower (dark red bugs the opposite)
3. normal green and red bugs stay the same.
All in all really good.
