That was really fun! I love the artworks and the nicknames for the characters. I liked figuring out which pilots and mech suits to use! The setting is super interesting, it reminded me of the Wasteland series or the Brotherhood of Steel.
Personally I think what would be cool for future versions would be more upgrades (and maybe a toggle for perma-death? 😈) I look forward to it!
It's really cool that you made this with pygame, mad respect. It's a shame so many antivirus programs seem to freak out with pygame games :/
