Me again. Hehehe.
I played it all over again (top 1 high score :P)
I think that if an asteroid trapasses you, it would be a real big problem ( looking at the story, the asteroid hits the earth, etc.), and the only in-game penalty is that you lose some money. But at the end of the game, the money doesn't matter, but the fiinal socre dous. Sou, i think that you would add this penalty at score for any asteroid not destroyed.
And another two things: it really needs a pause button (almost died when the phone rings) and a "Leave test mode" button.
Hum... I liked the style, but I think you should do some major improvements to your game. For instance, the game is very very [...] very easy. I mean, I got through all 10 levels without recieving a single hit, completed the 100k cash easily, got the 200 healthand completed the game... In my first attemp.
And it would be more interesting if you add some more stuff, like different asteroids, more upgrades, etc. Anyway, I liked the music. 4/5 for you. :D
Ah, I forgot. You could add some power-ups to make the game more interesting, like more powerful weapons, health packs, a little better graphics, and HIGH SCORES! ;)
