Check. I keep this in mind. I also implemented a room that requires the player to bomb over spikes. It works both ways. But why not just walk? That is where solid combos, and bomb flags come in. This area is optional though, and doesn't have to be completed by those who don't wanna blow themselves up.
I don't have any tricks to offer per se, but I will add this: I am a boomerang kind of guy. I will use this in every way at any time. It can really help significantly against -almost- any thing.
