Charming dialogue and impressive visuals. Text scroll could be faster or when you click it completed the text animation rather than skipping to next line.
The camera point of view is pointed downwards quite far, which I came across a similar problem when making my game. We increased the FOV of the camera a bit so you can still see what's on the floor.
The combat sequence is pretty cool, and impressive for the short time period. Monsters phasing through the floor when you kill them... well, it's a game jam!
The dice rolling on the screen is cool; the music transitions are also good.
It's good that combat is turn based, it especially works for a game jam where fumbling with a new game's systems can easily kill you through overwhelm-ment.
Having tile based random combat makes balancing difficult, but the upgrade system gives you a good way to play on!
