I thought I had to wait for the men to line up with the line for perfect, and I couldn't figure out exactly where to line them up to get perfect. Took until stage 4 to realize my mistake.. Shoot them as soon as possible :D :D
I would personally scrap the rogue and mage in favor of equippable gear. Higher level enemies/bosses drop higher tier gear and increased drop chance etc. Keeping the gear through ascensions would be nice too
