unfortunately I had to cut coyote time at the last minute due to time constraints, and jump buffer takes long enough to code that it wasn't really on the table given how much other stuff I ended up having to cut. :/
there's a lot more that goes into coding those mechanics than just having delta?? coyote time requires setting up a timer that resets and increments at the right times and also is linked to a mid-air jump, while jump buffer is another timer that needs to be set based on jump input and cleared upon being used, plus a lot of other tweaks to avoid things like jumping twice rapidly from a single jump input.
