Early answer :D Can't answer the first one because i haven't learned it myself yet :p
For 2): Yes, it's literally just practice, no tricks unfortunately. All i can say is keep your water shield up at all times and use your fire when the mech is taking its distance, so that you don't have to deal with the rocks and projectiles.
For 3) The best way is to get the 3 mechs as close together as possible and then jump and ground punch. This punch has a ridiculously big range and can easily defeat the mechs in 4 or 5 times.
Maybe let every skip have its own page? So we could go into detail, add pictures/clips and then have one page that goes over a whole route but refers to those skips with a link to the page.
Swag list needs to make it for sure. Also i'd love to have a place where we can put theories about the game's story, although i don't know if something like that belongs in a wiki :p
By the way for the people that couldn't participate, here are the results:
- Méléagant
- SamuraiBlue
- Maitre_Polia
- Celulith
- RainingEndavor
- Zet
- romibi
- Xycon [never finished Kappa]
Hope we get to do this more often as well!
