There is more to it beyond "There is no escape" and there is an actual ending. One of the updates I'll be doing after the jam will hopefully make that more clear, but it's a loop, and things you did as you went through the first time remain as you go through again. You can continue playing if you wish, or check the walkthrough video I put up on YouTube if you prefer. I'll also pass your note about the music along to my husband, I think he did a great job with that part!
I appreciate the note about the jump button too, but I am just the opposite. Several games I've played during the jam have featured W for jumping, but I'm so used to SPACE, it was causing me problems! I was thinking to just allow both in my update, or perhaps a way to remap the keys.
