concept: _UFO 50_ max cherries speed run

Obviously "All Cherries" as a category is essentially infeasible due to games like Rail Heist, Rock On! Island, and Grimstone taking over on the order of hours individually, but just choosing a subset of games feels very arbitrary. So instead, maybe select a chunk of time arbitrarily (two hours? three?) and say "the best run is the one that gets the most cherries within this time". That way, if a given game gets a way faster strategy, it can be routed in; there's also a lot of toothsome choice between which of the games you do or do not include, maybe even with differences between runners
