I get the title screen, then some random key presses got me to a chapter 1 and char select screen, but I can't work out the controls or progress beyond that.
When you've spent a good while working on a game, it's easy to forget that the end user is thrown in at the deep end and doesn't know how things work at all. You can address this by providing some guidance in the readme, or even add an in game to guide the newbie through the first steps (most people won't read the notes, they just dive right in).
I know seeing 'Press Start to continue' at the start of a game seems like stating the obvious, but it's better to provide too much guidance than too little. I saw the 'C' and 'X' prompts in game, but they just seemed to shift me back and forth between the start screens.
What I did see looked good and seemed to run OK, but I couldn't move on to the game itself to provide any more feedback.

Yeah it's hard to take a step back when you're right in the middle of it.
At the title screen use the arrow keys to move to instructions, then press x to enter. The rest should be explained there.
Basically the movement scheme is-> arrow keys to move, x to select.
