It's really funny to think that "Lustre" and "Crystal fusion" landed in the same Gauntlet, especially when the latter has aged so terribly in comparison to the former. I'm sorry I have to admit this, but "Crystal Fusion" is way too cluttered and messy for my own personal liking. It might have been somewhat decent at the time, but now it just looks like a rather clumsy 'fusion' of glow (lots of it, in fact!) and questionable gameplay. It also doesn't help that obstacles feel somewhat obscured by the level's decoration at points. I like the concept that the whole level is escaping from a mine that is flooding with lava, but aside from that, it's a relic of early 2.1 that (in my opinion) hasn't aged too well.
