Thank you! I'm happy you enjoyed playing it! I enjoyed making it :D
Yes, one should never underestimate the importance of having good support tools when making a game. The AtlasMaker I wrote has been invaluable for this project and I simply couldn't have done it with out it. Also I used Tiled for creating and editing the areas. I wrote a custom area exporter for Tiled so that I could load the areas straight into the game. It's things like that which really allowed me to focus on implementing the game mechanics. Each of the mechanics are fairly simple to implement but together they add a lot of value.
I also have decades of both dungeon crawler programming and gaming experience to tap into, which is always a plus :)
My take away from this jam is that I learnt how to implement pathfinding using A* and that I learnt to make a game in love2d/LUA for the first time.
