I didn't even know this was a trophy until after beating Lava for the first time and this came up. I hardly boost unless really desperate.

got this by accident, i rarely boost anyway, got this the first time i played it (after the trophy support updates)

First silver trophy I got. Very easy though.

This was the easiest medl to get in my opinion for this game.

yeah SUPER easy. First one I got and like others, I didn't even know there was boost at first

Yeah, uhh.. I didn't even know about boost when I earned this hahahaha.

Yh, this was way too easy for a silver..but hey I'm not complaining !! lol

It might be a bit tempting to not use boost but if your surrounded or going to be jsut use the flamthrower things and swirl it around you, it should work well enough for you to make an opening.

Yeah I agree. When I didn't know about boost I didn't use it, so I ened up beating the first level without it.

I think this is probably the easiest silver trophy in the game. Just play the first level on easy and don't use the boost.  Simple.
