The animal eat animal games have always been a little fun. Bad collision though, and it doesn't warn you when you can tackle the next dog. You just have to figure ~10 dogs after a new one shows up.
Followed the walkthrough provided in comments. Took 3 times before it sync'd up with the spawns. Money was definetly tight until missles came in.

@BlockJuice In the options menu you can turn off the music and have it FX sounds only, or you can mute it totally. Impossible awards are meant to be impossible unless you are dedicated.
This has worse rng than WoW if you can believe that. At one point I had 6 greens and a bunch of sporatic reds and blues. Took forever before a yellow showed up. 187500 is my top so far.
Not bad. Interesting to involve point and click with a scrolling plane shooter. The shield didn't really work out for me. Stayed with Super Beam and Lightning combo.
