Hey your comments were really encouraging.. thanks again for playing my game! Check out the project for an updated version (just released). I included an expanded source code file as well.
The updated version is great! Love the upgraded difficulty, and now there's a timer and an end to the game!
I got to 948, just about to beat your 960, but I was too aggressive, trying to kill other grasshoppers and I let 2 sneak by, and lost with only 4 seconds left!
