This is a beautiful, insane, epic story idea and this first chapter makes for one hell of a game! I just finished and realized how many slams and jams I missed the first time through. Now I am forced to join this fucked up topic that has filled up with psychos just to tell you that if you make more chapters, I will play every single one of them and encourage everyone else to as well. I haven't played such a unique gatdam title in years! If (when) it becomes a longer saga, this could take the place of Earthbound, in a way, and that is saying quite a lot, particularly for a FREE game.
My favorite parts of Jam: Gaiden were when
Charles Barkley slammed and jammed the hell out of all those fools, for his son Hoopz. I also absolutely loved the inventive fighting system! It was complex enough to be satisfying but simple enough to be action packed. BSUAJ:G takes it to the limit, and doesn't stop until the timer runs out, even the parts that made me cringe because they were borderline racist and/or sexually naive/criminal. That kind of gritty weirdness is what the post-cyberpocalypse is all about, I suppose, so we all better get used to it while we still have the freedom to take it to the hole in a pre-cyberpocalypse world.
The only suggestions I could possibly make would be to next time add even more powerful slams and also longer jams if you can, and just to make it longer in general! For instance:
I was excited to reach the map screen, but then disappointed shortly after to find out I would only be going one additional place from Neo New York. All the same, none of this will remain a complaint upon playing further chapters as they come out! I can't wait to play as Hoopz Barkley, and HACK VENDING MACHINES!! (please please PLEASE make that joke a working sidequest, in the name of Shadowrun and Decker)

Thank you to the whole gatdam team for all your hard work!
