I found this game very amusing. I liked how you played around with the different physics, catapults and swings and especially lvl 16 very interesting. 5/5 from me
I just scored 10,592,679 points and got to lvl 26.
Best startegy is to only upgrade multi shot and shot speed until they are maxed and try not to lvl up because its easier to get combos on low lvl enemies.
