I stopped at the point I did for two main reasons: 1. I was tired and 2. I knew the next level on gets ridiculous for playing Eclipse mode solo - it starts spamming the red guys and gunners which would take forever because I'd be spending most of my time dodging rather than fighting. I figure this was more than enough as a proving of skill, and from that point on the game becomes much less fun and much more of just a game of attrition between you and the robot enemies, at least if by yourself in Eclipse mode.
