Daily Death #3: Caveblazers daily and a big gun

I like games that have 'game-breaking' items. By which I mean, games with certain items or facets that seem so wildly different or powerful that they seem like they'd break the game, only they don't. The jetpack in Spelunky is one example. It allows you to hover over all the enemies and spike traps that had formed so much of the game's challenge beforehand, effectively skipping parts of each level... But if you've ever used the jetpack, you know it's not quite so simple. You'll still fall on some spikes and die.

Today I found a weapon in Caveblazers [official site] that feels game-breaking.
