Interesting as a prototype for part of a merchant game? It seems like a good concept but needs some work. MoreOrfLess is fine, but that's random so not fun strategy. All the manipulating stats is no good unless "Persuade" action is available, so the random actions concept doesn't work with this limited pool.
Maybe "Persuade" needs to be always available? And then you have a larger deck of options available to allow you to manipulate different stats on yourself or the customer?
I am curious to see where this goes or how you're planning to implement it in a fuller game! But can I suggest you enter jams with a more open theme or specifically designed around getting feedback, this doesn't feel like it was designed for this jam.
