Golly! These are buckets of insight. Firstly, thank you for that! I'm surprised that you reviewed it from a game designer's standpoint; you've among other things made a point I hadn't realized about the movement, which I'll have to keep in mind for similar future projects.
Moreover, I definitely see the issue with presenting the mechanic. I believe I could have made it more clear with more experimental opportunities for the player, in due time. Next jam, I'll get quicker to the point!
I'd love to take this a step further. We'll have to see how that goes. Regardless, thanks again!
