>>716246214Banjo and kazooie worlds are defined by collectibles you need specific abilities to get and each ability is usually a collectible as well. Not only that the abilities are frequently used after the world they are introduced in.
Bananza has the different bananza forms but outside of the ostrich having a useful general platforming ability you never actually use them again beyond the world you found them in, everything is designed to be plausible by base dk outside of the few specific instances where you have to use the bananza from that specific world.
The game is copying 3d marios style where you already have everything you need to finish the game and theres literally next to no backtracking.
The only instance of backtracking ive encountered is needing the ostrich for a banana in the freeze layer thats in a house floating in the air.
