Hehe, no-no-no, not the last one XD I passed the last level about a year ago, that was when I didn't know about supergems and all, I was playing straight, mostly using pure gems. I don't like mixing, in general ^__~ Now I can't get to the last level cause... well, it got boring. I can't make myself pass the levels fast and I always want to get the maximum of it. And it means an hour per level, with all the slowness and overangering the last wave to waste too much time on it. And there's no point now that I got all skills maxed. Supergems are joy killers...
Anyway, someone said the last level has a smoother HP curve. How about id#12, endurance? ;) Can you get to 200 wave there? I failed.
And sure, I could get some screenshots if you tell me where could I upload them. And my PC is not this lame, 3GHz, 2 core, Crysis goes just fine. I guess Gemcraft is even cooler than Crysis, judging by the lagz XD
