If you come to the Big Chest before collecting the Treasure Key, you'll get this message:

This is what getting the Treasure Key looks like:

Once you have the key, you'll be able to use it on the Big Chest:

Like I said before, the Treasure Key only opens Big Chests. Only Boss Keys open Big Locked Doors. I'm hoping this becomes pretty innovative and that I can create some unique dungeon flow using this.
As far as progress goes, I've finished Level 1 and the surrounding areas. It's getting close to where I can release a solid demo which spans past the intro area to a mini dungeon and then to Level 1, along with some story. However, I am debating on holding it off for a while until I have more areas for you to explore, because right now, it's just a somewhat linear path through what I have so far. The full game will have a boatload of exploring, which I want people to experience when they play this. What do you guys think?
To close us off, I'll leave you with a teaser shot of one of the new areas:

That's all I have for now. I hope you enjoyed this. Thanks for reading and have a nice day!
