Like I'm going way too fast and jumping way too high, and I also usually fall like all the way to the ground and miss every encounter, I'm not even sure where I'm supposed to go.
This is still a great game though!

There are certain jumps that are intentionally impossible or only possible under certain circumstances, as well as some very tight jumps or jumps requiring running starts, which might be part of the problem you're having.
Additionally, there's a door somewhere in the level that takes you to a boss battle, after which you go to the next floor.
