This is such a cool idea for the jam theme! The combination of Bookworm-style word building with roguelike combat mechanics works surprisingly well, and the gameplay loop feels really addictive 😄
I especially liked how forming connections between letters directly impacts combat — it makes the theme feel naturally integrated into the gameplay instead of just being visual flavor.
The artifact/special tile system also adds a lot of replay potential, and honestly the whole project already feels very polished for a jam game. The UI is clean, easy to understand, and the progression feels satisfying.
I could totally see this becoming a full game with more mechanics and content. Great job!
