I got to a score of 680 after causing more trouble than a Sydney climate protest.
Its good fun throwing those sponges.
Things I would suggest: some squelchy sounds when you throw and when the sponge collides with buckets, cars, trucks etc. Some music would be good also, maybe some Aqua ;)
Also I'm not sure if I want a crosshair or not, maybe make that optional. The more I played the easier it got to hit targets, so I'm undecided about that one.
Its a fun game :)
