So I made an account just to comment on this. I listened to about 3/4th of the podcast on my commute and it peaked my interest. I very much liked the concept itself and was excited to see there was a build where I could see it.
I do recognize this is a prototype so I'm not going to judge this as a complete game, but i figured it might help to go over what I liked and didn't like.
The base interface of the game is simple but is fine for this game since it's supposed to be a very quick kinda "see how many different results you can get" kinda affair, so I don't think you need to do much more than that.
I liked the dialogue you get with certain choices, the best one by far being the "apply clown makeup" once since I saw that effect the startup dialogue for the battle as well. That seemed to be the choice that had an effect I enjoyed the most, even if it was just getting to see additional dialogue.
I like the idea of the heroes changing based on your choices. I thiiiiink this might be slightly buggy since I got one path where it said something along the lines of "The Hero is wearing None" but again, this is a prototype.
The things I think need to be improved are more actual player character dialogue based on your choices, since those felt like big payoffs, seeing a personality develop based on your choices. I'm sure that's an intent for any future builds so that's a minor point.
One problem I DO think should be addressed is the battle at the end. In most of my runs the battle dragged on for quite a bit and honestly it was the least fun part of the game to the point where I stopped reading the battle flavor text. Granted it's supposed to read like a typical RPG battle, but it's not fun to click through that without user input for more that like one or two "rounds" of the battle. Like if there was dialogue during the battle or if the battle was kinda fudged so it gets to the end result or the unique dialogue mid or at the end of battle super fast, then it would be fine, so it is fixable. Again, it does mess with the kind of "this is a JRPG" aesthetic a bit but getting to the more interesting bits faster there I feel like would be a MASSIVE improvement.
So those are my thoughts. I did 4 runs, did not succeed as of yet but I enjoyed the concept enough that I wanted to run through it a few times, see what would change. In a completed polished state, I feel like a lot of people would play this as a curiosity since it is quick and would be fun to see what variants exist, so I do hope there are future builds of this just to see how polished this can get. Good work so far. Hope my comment was helpful.
