Wow, lots of comments! Thankyou everyone for your feedback.
In regards to the theme, one of our first thoughts when hearing "You only get one" was a typical roguelike game, where you only get one life, and as a result random elements and quick progression are introduced to make for fun when replaying after death. We maybe didn't get enough time to implement everything we wanted to take from the roguelike genre, but we think we got the core elements down and were pretty satisfied with that. Unfortunately for people unfamiliar with roguelikes the theme might not really shine through :(
Gold was something we wanted to have a use for in game, but we didn't have enough time to implement. We wanted to have a shop room that you could randomly encounter and purchase items from. In our second Ludum Dare game 'Stranded' we had pots in our game similar to this and one request we kept getting was to put something in them, so we are moving forwards at least! We also think that even though gold isn't useful in game, it still feels pretty fun to loot.

The scrolls don't actually cost mana. Not sure what was happening there for you.
Again thanks everyone for taking the time to download, play, and comment. We worked really hard on this so it's really great to see people take the time to post some thoughtful comments about it here.
