I understood you you were taling about mechanics ;) My question was more about: would you play a longer game (2h-3h?) with the same mechanics? I have some ideas to add new mechanics for new puzzles, just wondering if it worths the effort :)
Personally I would, but not sure that I alone would be even close to worth it :) I'm sure there were other earlier examples, but I think back to the Genesis game The Lost Vikings, and at least since that game I've loved playing puzzle games with multiple playable characters on screen at the same time (as long as it's not "real time").
