I just started playing today, I'm just level 4 and I did my first arena fight. After I won I got 25k gold, all the speedy awards (i.e. winning level 53 in 15 turns) just for the arena. It's a weird bug, but it gave me a lot of extra money.
I really can't see what's the point of the stars. They don't give you any money, they don't unlock anything and instead you just have to destroy some really high hp monsters to get them and risk the chance of dying and losing the stage for something that doesn't actually give you anything.
I was kinda dissapointed when I leved up and then discovered that 20 already is a maximum level. I always love when you can get to a high level and feel overpowered in a side-scrolling shooting games.
Used a coin to stuck my right arrow key down, went to the kitchen and when I came back I saw the snail starting to bite the leaf. Sat down, grabbed my mouse and accidentally hit the back button. Have to start all over again, damn!
FFS, this makes me angry..
I have reached 2mil+ many times and after that I hit the mine or get abducted by UFO. This this I reached only 1,5 mil feet, but I had 151 nuclear bombs and 9 golden shots left...
