Demakes are an interesting concept. For example, how little could you get away with doing for a demake of the first level of the original Crash Bandicoot? By that I mean, how little time could you get away with spending on code and graphics and still have it be recognizable by someone that had played said game in the past? How little and still have them identify it as a version of Crash rather than just being reminiscient of Crash? How little and still be visually pleasing? How little and still be enjoyable to play?
