WarBell

As the Readme promised, this map has some brilliant new ideas! From the praying for health, to the sacrificing players, to the repairing and ringing a bell, the maker of River has delivered another excellent map!
(All it needs are secret rooms.)

Any screenshots?

No, I'm too lazy, I have to go, and Wolfmap.de doesn't let you anymore.

That's the sacrifical altar. Put the Book of the Dead there, build the bell, ring it, wait, walk into an orange column, die, watch it turn red, repeat twice, and win.
