Yeah, as well as remote bombs, we can have bombchus
Roc's cape will be good, although it would only last a limited period, or you'd be almost indestructable.
Armour we could have as Nayru's Love.
Hmm, just had an idea, how about a level with bomb flowers, which when they get set off, there's a chain reaction round the level?
There also HAS to be levels with conveyor belts, tunnels and warp points - it wouldn't be bomberman without them.
