I was so upset when I reached the end of this game. I wanted to drop to my knees and scream "NOOOO!" at the sky, but I'm at work on lunch so that probably wouldn't have been the best idea.
I really hope that you guys continue to work on this game. Add more levels and maybe a timer so you can see if you can beat your best times (a simple timer and saving the highest score would add replayability without spending a lot of time adding more levels).
I'm sure you guys know all this. I'm just hoping to spark something so you'll want to add more to the game :-P.
