While it isn't complete, it's playable, has a lose-state, and demonstrates the main mechanic: rob graves to collect resources used to raise an undead army. Use your army to fight the cemetery guards.
I think that the game play idea has promise - I'd be curious to hear people's thoughts about it, especially any ideas to take the concept further post-contest.
We used Godot to create the game, which I'm still pretty new to. We used the "GoRogue" C# roguelike framework to handle the map, line of sight calculations and some other conveniences. The tilemap in Godot is constructed and rendered dynamically every time an action occurs.
