I'm running on a crappy laptop too, and it lags like hell. But, I got the BOTD. in the third level, make sure you get those 2 red targets, each are 10k points, get both for easy 20k, then you need to headshot as many as you can. Camo headshots are 3k each, so get 2 of those, and that leaves you with earning 6 k on the normal guys. Just make sure to get the red targets.
I think option to charge in battle should be in addition to the slightly delay turn command. It takes too long to charge, when my strategy might hinge on only delaying to let someone else go first.
Since the game lags a little from time to time, I think that there should be an option for no animations, lowering the quality, it still goes at the same speed.
