Thanks for replying! If I were to make a suggestion, I would agree with a more 1v1 format, and to even out to playing field so that the player isn't just getting buffed, I might suggest a format like the original buckshot roulette where the NPC fan use items for their benefit. However, that would be a lot of code to add, so I understand if you want to at least hold off on that for now.
(edit: Just overall making it so that the NPC feels more lively would be a good start visually, and in my opinion, after adding more control to the player, but then working on the NPC behavior would be a good start, even if it's just a very simple ability that they can use or something. Just getting a basic start on NPC behavior would be a good setup for very dynamic and fun possible NPC interactions down the line if you develop them over time.)
For now though, I'll hold off on any further suggestions until I see the next version so that I know what I would actually be giving feedback on lol. Godspeed to you!
