It's a little early for submissions. If people want feedback or beta testing this early they can handle that through the normal channels.
[The Submissions Office Hours: Mon-Fri 12:37 - 12:39 A.M, Sep. 20 - Oct. 5]
Could probably set it up so that if you beat the 3rd with under 10 deaths it will lead to the 5th. (assuming the 5th will be decently challenging that is!) Otherwise I'm not sure. Probably depends on the quest.
