MoneySeize is a great example of retro jumping and collecting. Your hero, of sorts, Sir Reginald MoneySeize II, Esq. needs to collect all the gold coins he can find, to fund construction of the tallest tower in the world! No princesses to rescue here. There are 50 stages, with 1010 coins to find. Stages range from super easy to almost impossibly difficult. It even comes with the disclaimer "this game is very difficult" - platformer professionals will love it. It really is great, though, and our rotund aristocratic hero can do everything an Italian plumber can - while wearing a top hat.
