Played through the game, it was good! A little hard to get into some place because of how fast the player moved and how big the player was, as mentioned. I've seen some platformers that are pretty unforgiving and have you restart a whole level if you mess up, and it seems like you guys thought through some edge cases so that it wouldn't need to happen. Great job.
Also, I didn't realize this was pixel art until I looked at the tags. Looks unique and great for pixel art, to me. And I loved the dedication to Josh's wife, very sweet.
