You've gotta be kidding me. Level six for final gate? I'm level five. That's ridiculous. Please, don't make it levels. Make it kills or something. If I miss even a single orb, that could be the difference between me finishing the level, or having to start over. Bloody flawed.
I think being able to see the firing arcs of your own team would be nice, because half of the time my team don't attack enemies. Also, I also agree with RogueLemming, some of those things being fixed would be nice. Faster gameplay is need also.
