The idea was "Into the Breach" with Castlevania style items and characters. It was too ambitious for one week though, I hadn't done any game dev in over a year and I had no idea what the best way to implement a turn based game in bevy would be. We used sickle ui which I wasn't familiar with either and I kind of struggled with. We had a lot of things that were almost implemented but we had to abandon as we just ran out of time.
The tower was meant to be able to shoot in four directions but didn't have time to implement it (or remove it before we published) , you can recruit new units if you build a tavern, blacksmith does nothing and is just a waste of gold. I wish we'd had time to implement tooltips and stuff.
