this is not a highly overrated game for the critics out there, this game is an improvement on the first (traps, improved mana pool, level type choosing) and is indeed much easier (the epic bosses in the first were almost completely invincible). Besides, you have to realise that some of us out here are not so sceptical that we need a perfect game.
oh and the gem bomb thing - 1, aim it properly, and 2, better gems mean better bombs, and 3 - someone tell gameinabottle.com about the glitch that stops them damaging some times >.<
