Battle, by 
I really like how this looks—the colors work well together, the leaves are charming and make the screen look alive without obstructing visibility/gameplay—but not how it plays. There’s definitely room to explore how to use Hurt events (and other things that hurt you) in multiplayer levels more, but I don’t think this is the answer. Right now if you want to get the carrot, you have to take a sucker tube out of the carrot room and into a bunch of Hurt events. I’m really not sure what the reasoning here is but it’s not enjoyable.
I wonder if this level was only tested in local splitscreen multiplayer, not internet/LAN multiplayer? When played in local splitscreen, the various destruct blocks respawn after a while, and even a bunch of enemies(!) appear, but neither of those things happen otherwise.
The layout is odd for a battle level. There’s only one start position, and from it you follow one of two linear paths (one of which loops back around to near the start) in search of powerups. There’s not a lot of stuff to pick up between powerups—and most of what there is to pick up is gems, which are useless in battle—so battles may end up clustering around those powerups as players who already have them defend their positions against their recently respawned opponents. The flow isn’t the smoothest around: you can bump into walls and stuff trying to progress along the linear paths, and again there are Hurt events to contend with.
I dunno. I’m reluctant to opinionate too much about the non-technical aspects of this level, as it’s clearly aiming for a very different style of gameplay than most battle levels (especially when the enemies work), so how reasonable is it to judge this by the standards of a more traditional style that it’s uninterested in emulating? Maybe if I got some more people together to play this with, we’d have a good time advancing along the level’s main linear path, kind of like an assault level. Maybe not. But the graphical experiments going on here are certainly pleasant to look at in the meantime.
