Made the third loop! Besides Batsugun, this is te first Toaplan game I have been able to loop twice, which feels pretty sweet. The third loop is pretty brutal, but even though I didn't make it past the early stages, I think it's doable with most of the same patterns from loop two.
I think I'll probably give this a rest now and work on Same Same Same as I have my autofire pcb back and after play a few games late last night, feel myself getting sucked in...
