Thank you for checking out my game!! Yeah the glitching was something I made peace with early on. I thought it wasn't too visually disruptive to cause epileptic issues and it added to the janky charm that a game jam build can have. Though I am glad you like how the movement feels, its something I tend to gravitate towards when I get a chance to program a game (the very small moments I get it do that)
Regarding game instruction/clarity: I made my peace that I didn't include enough direction/feedback into the build and so I accepted players would be confused. Time caught up to me (plus other things!)
However I do want to field to you (and others that had a similar issue) this: If I were to add a faq regarding to how to navigate the game and explain how it works in the page description, would that be an acceptable addition?
(Don't feel like you have to answer that, I'm glad you checked out the game and left a nice comment!)
