Ah yes, that is true. I just went with what many other games did, I'm talking about E over D. I myself change use bindings over to my mouse wheel but not everyone does that, so I went with the most common option. For the controls screen at the start, it's supposed to wait for a mouse click before disappearing, but It was added literally minutes before submitting so it could probably be an oversight. Now that the Jam is over I can start fixing the game.
