Finally complete. Could really have done it MUCH earlier, given how easy the final level was, but ah well. Slightly disappointed with the bonus 'beyond corruption' mode though.
I've been assuming the level only lights up after you complete 'everything' and gain access to some other mode which relates to the block you can kinda see at the bottom of each level.
Rather disappointing lack of anything after you beat the bonus level. Other than that, it was excellent. Frantic is more polished, sure, but I really like the ability to replay levels which I don't think Frantic allowed.
None of the levels are difficult per se, but some of them are really frustrating, and no amount of practice (short of learning some very precise timing) will actually make you batter at it. 2/5 because of this.
It doesn't have a very balanced feel to it. So many times it's been easy all the way to the final wave, and then you just get massively overrun. I'm all for challenge, but there's no learning curve here.
If "Fast Learner" makes the experience earned go up by 5%, but the experience required increases by 5% each time (I'm assuming – 1000 first, now 1200), then what exactly is the point of that skill?
