Here's a shortcut for chapter 3 (got it in 41 seconds): First, jump off the cliff and let you fall down all the way to the bottom. Then restart immediately by pressing space. Get to the cliff again, but instead of jumping, you should walk off the cliff. When you're 1-2 seconds away from the cliff, jump. You will jump in mid-air which causes you to fall much further than usual (you can see this by watching the cliff disappearing much faster). Your fall will end on the cliff with the light on it. Just walk onto the light and you'll beat the level much faster than required.
@lugito: When you've mastered a weapon, it appears with a crown above it which is even visible in the Arsenal screen. And about those treasure chests: That's part of the challenge, and besides, when you open one, you get a message saying which one you just opened.
Ahh, finally a puzzle game I was able to solve without a walkthrough. I even got the last badge with one level to go and without replaying older levels :).
The fact that you can listen to your own music while playing the game just makes this game awesome. And that's even without taking the game itself in consideration.
First of all, why does this game have such a low rating? It really reminds me of Amorphous+ and that's nothing but a good thing. I love this game, but I think it needs a bestiary, so you know which cell has which name (useful for the Casualty-Extinction badges). I also think this game could use a tracker, so you know how many kills you still have to go for the badges. But all in all, an easy 5/5.
@ Guardian: The difference is that Gold Packs contain cards from the Standard Pack, Nexus Packs contain cards from the Nexus Pack and Blight Packs contain cards from the Blight Pack. There's no possible way of getting a Nexus Card through a Gold Pack and vice versa.
Guard: I'm a professional guard. Me: No you aren't. Your boss is dead, I was standing right next to you for 2 minutes and yet you only noticed me when I tapped you on your shoulder. So shut up.
Guard 1: Where could he be? Guard 2: Well, I see a trail of bloody footsteps leading behind that crate over there. Guard 1: Shut up, I know what I'm doing, I'm a professional guard.
