Your games are right up my alley. I really enjoy playing them!
I think something can be done to utilize the skill points, the mall setting, and make it a more active experience to play. My initial idea is to allow the player to trigger events using the skills points, such as a sale in one of the stores, causing people to cram in.
I see you already have plans for similar ideas to ensue chaos, so I can't wait to see where it goes!
