Here's a "level" guide :p
Levels 1:collect everything on sight Level 3:your first red, collect the green orbs and the red's green orbs, dont worry about dying and prioritize reds. Level 5:your first wave of orbs. only collect them if you are in range but is worth more than the reds except for Orion at this point. Level
I might be unlucky, but the stupid wheel always goes on death for me D: and here's a tip: try not to have stats equal to the "boss", you will always fail because of who goes first.
