Momentous. As somebody who played the original SRB2Riders back before it was even an EXE mod, I know quite a bit about how far this thing has come, and after getting a controller to work and diving in properly, it's absolutely breathtaking to see this spinoff of a spinoff port stand so tall on its own two feet. Battle mode in particular was an absolute joy to play, and the bomb kart mechanic kept things engaging no matter whether I was winning or losing.
In the DooM community, a project like this would be called a Total Conversion, but while technically accurate it would be a disservice to think of SRB2 Kart in those terms. This is its own game, period.
And a damn good one if I do say so myself. Congratulations on finishing this tremendous release.
