The arenas need work. They are all the same with different interiors. Unless you had events that changed the part inside, like making the water arena into a fire arena, then it would be ok. But you used the same one for each. Try to make each one different.
Also, the Warehouse is really repetitive. Make different size boxes or other things.
But the Volcano looks great.
the arenas are meant to be the same type of arena, but the only good arenas are fire and air i do confess
it is impossible to event brick changes
if youve ever been in a warehouse, they are very repetitive. my ware house is a DM, but is still a warehouse, thus repetetive
oh, and there are two sises of boxes, and different shelves and fallen shelves and wood and other stuff
:D have fun with the volcano!
