After a little while of gameplay, you get the hang of the rules. It's mainly just how much time you want to commit to the game. Also, what is difficult about the controls? I'd like to know in-case I ever feel like updating the game after the jam.
The latency (delay) after key press was annoying and made it feel less responsive than it could have been
There is a tiny cooldown after you move a space. Try holding the movement key for the intended experience. Unless I'm understanding the issue wrong...
Maybe on the html build there is delay, but I'm not noticing it during testing.
