Overall: Didn't really learn optimal setup, was more playing with a casual mindset to the fights rather than going for optimal setups.
Stage 1: Bad fights at start, ok spawns, overall a bit slow.
Stage 2: Decent Helicopter, but in US version this level seems way more random in time.
Stage 3: Good overall, played a bit safe, slow boss fight.
Stage 4-5: Worst stage 4 ever but best stage 5...
Stage 6: Oof, many missed despawn, played sloppy, etc.
Stage 7: Had a streak of just bad luck on this stage so happy I didn't die.
Stage 8: failed all 3 fights in some way, but still good enough.
Stage 9: Best ever, can't complain :)
All in all, I think I can push this to low 20. But goal was to learn it well enough to submit to live marathons and if it ever get accepted a grind for low 20 will start :)
