Finally finished all seven levels of the Grand Prix! It's kind of fascinating to think back about how much I struggled to get through Level 3/4 when the game first came out, and then today I was able to get through 6 and 7 without too much effort. Playing in the GAF lobbies and doing ranked matches really taught me a lot and helped me become a better player, and this is evidence of that.
but yeah, I'm pretty proud of myself for accomplishing this. I did it all with my usual Twintelle loadout (Seekie+ and Popper) and never switched to try to make things any easier. Not that there's anything wrong with using a more optimal set-up for certain characters; it was just kind of fun for me to try to figure out how to make my preferred set-up work in different situations!
Grats Felix! I still haven't gone past 5!
I am going to finish up clearing 4 with every character/default arms first up and then go through 6 and 7 with Ninjara.
