I play GL Tron on my mac and beat the CPU's on the hardest difficulty. But this....I can't even get past the second level. It's just frustrating. There's a huge difficulty jump and the CPU's are spot on perfect, after about 12 attempts I noticed that sometimes they'd phase right through my line. Or I'd die out of nowhere. If this game had a little more work put on it I'd enjoy it a lot more. I enjoy the style of the game none the less. There's just some coding issues.
