Why not build puzzles first, then later do a game with the puzzles in it
i don't get it -- what would this mean?
I was referring to this:
(Bare in mind I know nothing about gaming, but...) Wouldn't it be possible to do both? Journey through the dungeon labyrinth solving puzzles to get to the next room/passageway/level?
Think of the "solving puzzles" as a very small element within the game that repeats. Creating these kinds of puzzles in a way that users can create modifications of them would be a good small start. Think of it as a practice run through in order to get people into the groove.
Puzzles are relatively simple. The problem is to create puzzles that are fun.
So, for example, a peg-jumping puzzle to remove all the pegs would be relatively simple. But it would need a twist to be fun. e.g. Cody must run over worm holes and eat the worms, but can only run over a worm hole once. Animation there is probably the key element to making that work.
But simple, simple puzzles like that would make an excellent start. Later, they could be incorporated into a dungeon game or whatever.
