For the weekly challenge. I've always loved RPG's, and while 2-color RPG's aren't as graphically pretty as some RPG's out there, it doesn't mean they can't be any less fun or immersive. :) In this scene your PC (a wizard named Kar) is preparing to take out an enemy in full armor using nothing but the spells you see in the spell tab at the bottom of the screen.
I've tried to make the mockup seem like you can actually play it, so for those of you who are interested, here's a brief overview of the UI:
In the upper left corner is the character tab. Clicking on the character's portrait would take you to the character screen, where you could see all the character's stats (skills, hitpoints left, mana points left, experience points needed until next level up, etc.). Below the character's portrait are the health points and mana points parts, which give the player a graphical representation of the amount of each he or she has remaining. To the right of the character's portrait are the training button (you press this to spend the skill points you earn each time your character levels up) and the inventory button (lets you access the items in your inventory).
On the upper right hand corner we have the mini-map. Pretty self-explanatory, I think. ;)
In the lower-middle of the screen we have the spell and save menu tap. The four icons on the left are spells or special abilities your character can use in combat, and the icon all the way on the far right of the tap would allow you to access the save menu (options: return to game, save game, load saved game, options, quit).
