Hmm... I don't think I'd consider it point leeching to jump through the floor. I can get more points by finishing the 25m the regular way and smashing barrels, especially on the first version of Crazy Kong. The first version is the one without the missing pieces on the 25m. On MAME, the ROMsets ckongalc, ckongs (to some extent), and monkeyd all are the first version. The second version (with missing pieces on the 25m and fast conveyor belts on the 50m on L=02 and higher), sometimes also known as Crazy Kong II, can be found in ckong, ckonga, ckongjeu, and ckongo. It's not as easy in the latter because the 2nd hammer is quite a bit harder to get.(posted 9498 days ago)In addition, I'd hardly consider anything that finishes a screen FASTER point leeching. Point leeching, IMO, is when you don't try to progress through the game, but hold back for extended periods of time to get more points.
Either way, you can't leech too many points in CK anyway...
