It's really good! All those maps, weapons...
I especially liked the Temple map and the Continuing Crossbow
What about having a mythical map that features mythical realms? I'd suggest a Realm of the Dead with castles, boats, bridges, and a desert-like sea below (which kills you when you enter), particularly for the next Halloween.
And, just as someone commented before, the April Fool's event should last for 48 hours. It was really fun, that big machine gun!
