this is on hard mode, it has more enemies and bosses have more health,but same patterns
yes,there is 2p mode and i'm not sure it's faster,bosses have more health and i found no way to hit simultaneously,also mickey is faster than donald, but i'm not sure whether you guys will accept separate categories.There is some small space for cooperation so maybe that makes the game faster.Jumping in donald barrel or genie hand for example.
i only TASed the first stage and i watched your first stage and you could have hit the crow with an earlier block to make sure you don't wait for it to go away.You can't swim with a block but you can jump on the water surface.
there's a part in the desert he simply stops walking,the fight against cannon boss could have reflected shots earlier,a lot of the boss fights don't look very optimized and i'm sure loses a few frames in movement as well
i wish i could TAS this but i'm busy so i'm glad you made this attempt,good luck on your future TASing but i don't think this is enough right now.
