I have to propose a casual game idea for a class, and I have two so I was wondering which one sounded better. One thing that is going to be a major factor is time, a group of people are going to have to create a game in just a few short months. I don't if either would be really feasible in that regard to be honest.

Idea 1: "myKeep"
Premise: The screen of your cellphone is presented as a castle. You can customize your castle with decorations, protections and units and either visit or invade other "castles".

Idea 2: "Exilir"
Premise: You are an alchemist that travels between three different stages collecting ingredients and solving problems with potions brewed from those ingredients.
