This is pretty cool!  I liked starting with the flip.  Gives a nice brief before the level.  I got stuck immediately because I didn't know to hold left mouse, I only clicked it until it died and then had to read your description to get going again.  Move that level 2 hint up to level 1.  I really like the fill with green when holding mouse!  Very creative!  I thought the flip icon at the top was a G and couldn't figure out what it stood for until moments ago while typing this.  

Cool that it has an endless mode with procedural generation!  I also liked how the bugs would repel away from my mouse for a while after clicking them.  Nice touch!

I love the aesthetic. The game has a lot of character and is very satisfying to play. And the procedural levels are really impressive too! Really cool entry but definitely needs a cover image so more people get to play it!
