Chip 'n Dale: Rescue Rangers 2 is quite an improvement over the original Chip 'n Dale in terms of graphics and a whole lot of other things. Thankfully, the original game's solid controls haven't been changed. The plot of this game is that Fat Cat has stolen the Pharaoh's Urn and wants to use its power (for evil purposes, of course).
This run only uses Dale. It's an improvement of 00:45.28 seconds over fiskerN's second submission and 03:08.77 over his first submission. See the author's notes for more details.
See here for the 2-player run in 11:04.65.
