It wasn't a bad odd. There was simply something off going on while I was playing it, but that could just be me being rusty on platformers. Most games use [Up] or [Space] for jump, and your game has [Z] for it. Having configurable keybinds was a nice touch.
Hmm interesting, to me [Z] has been the jump for the longest time, and [Space} or [Up] feel clunky or unnatural. [Z] was also the default jump key in Cave Story, so it's kinda stuck with me ever since I played it. Pretty sure bunch of other games have used it as well.
