On the kkz-9940 download for version 2.0.0, with both NTT 9940 and 9944, there is an error when you parry (kkzHUD.mod.gml [L158,c45]) where the game expects a string but doesn't get one (I think it's string_length receiving a number). The error happens every frame after what would have been a successful parry, until the run ends.
I haven't had a good run yet but I can tell already that I like the character. Nice work!
(Also, I recommend removing the "kkz/" from the beginning of both load commands. If the kkz folder is not directly in the mods folder it will not find the files, but if it's just "/loadrace kkz" the search will work no matter what because load commands use relative paths.)
