First of all, i wanna say that the last depth was fantastic! I really liked it. Though i have some concerns about the order of the arenas. The first one was pretty easy (shock+beast+jelly), the last one (mecha + fire + gremlins) not really hard, because you were still able to run around and spam DA/Acharon charges. But the second one (freeze+fiends) - uhm... i died like 10 times maybe... Devilites can't be shiver'ed since this arena has freeze theme plus the arena size seems really small (maybe because of freeze blocks, attached to the edges), so you cant move around, not to mention the trojans... In other words, this one is the most challenging, and i thought the arenas are supposed to be ordered by the difficulty. So i suggest to either switch the order of last two arenas, or change the theme of the second. Well, it's just my humble opinion...
