[Boost King]

I just picked up my copy on my lunch break today, so I'm still at work now and wont get to play it till tonight of course. Any tips for acheivements, ie, what level should I do the game on, should I be aware of collecting anything or not using something etc?

I hate it when you get 50% through something and realise you've gotta do it all again without using grenades to get a acheivement. I'd like to know on stuff like this. If anyone has any ideas, let us know.
