At first I was like "OMG ULTIMATE ASSASSIN 3", but then I was like "hey... those achievements are mainly luck-based...", but now I'm like "**** this, I'm getting them all."
Great game... If you're a cheap-ass like me, just build a column of resistors (level 1!). They only cost 15$ to repair. Overall, this should be so cheap that you could repair non-stop. Remember to put the speed to slow or normal, because otherwise they'll break through anyway.
@gootfish: Kill 2 animals so they fill up the hole. This can also be done with 1 animal. If you want to do it without killing any animals, then you'll need some luck. Jumping and pushing at the right time is required, combined with a lot of trial and error...
For those interested: it is possible to finish the game with 27 lives left. Only levels 1-2, 1-3, and 3-3 require 1 sacrifice. All the other levels can be finished without killing a single animal. Good luck!
@silverdraggin: Had the same problem. Wait, damn it, HAVING the same problem. This just plain sucks, I just finished the game with every duck and now the strength one is missing.
Matt is the best person for getting A/S-ranks. However, it requires some thinking. Do not hold the fire-button constantly. Simply press it once every second to fire a V-pattern. In the later levels, this will kill most enemies easily.
1. Buy a Castaway feather.
2. Go to the 2nd or 3rd level.
3. Stay close to the entrance and get attacked by a snake or scorpion.
4. Use the castaway feather and immediately try to walk back to the village.
5. Stay the night in the Traveler's Den.
6. You'll now have unlimited money, health and level. Too bad you cannot walk anymore, but if someone can figure out how to walk... :)
