An early idea to develop "Jewel Thief", a game similar to this: http://www.2flashgames.com/f/f-522.htm but with more functionality, VS modes, online gameplay, guns and mario?
Given that there are many flash versions of this out there which will no doubt work with the wiimote, I might not be bothered to go ahead with this!
User has 3 men (lifes) to clear the game. Using the wiimote you have to gather to items while dodging the guards. If caught by a guard you loose a man (life) and all items are returned to their starting points and the level starts again. All items must be cleared to pass the level.
Extending Original Gameplay
The original idea is quite simple, so here are a few ideas to extend on it. I'm not saying that all of these would make it into the final game, tho without any of them I don't suppose there's any point in me bothering.
Walls (and electric walls)
Give extra structure to the maps, imagine it to be more like pacman in this sense, with pacman being controlled by a wiimote, and walls possibly electrocuting pacman (a bit like a wire buzzer game).
Instant death if you hit one!
Hidden/timed items with extra points
Kill the Guards
Give users a gun with limited bullets? possibly operated by a second wiimote? objectives could be extended to kill all guards as well as collecting the items.
import custom levels from a folder on the SD card.
allow users to set images for: bricks/blocks, items, characters, etc. Could allow for things like mario themes?
Using something like: Navarr's WiiBrew Internet API, have leaderboards for completion time and highest scores.
Race to collect the items before the other users, possible have specific colours to collect??
Online VS mode
As "VS mode", but online!
Online Battle mode
Include possiblities to play pong, brick game etc in the background while playing the main game? yea right!
