Maybe it's just me, but having some of the control buttons on the mouse and some on the keyboard was awkward. Also having the E for action right above the D I thought was odd. I would have preferred movement to be one hand and everything else to be another. You also didn't get much time to read the directions in the opening and I had to restart several times to memorize all the keys. But then, maybe I'm just used to different key layouts.
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.
