I enjoyed playing this one a lot. Great aesthetic, art and music both complement each other very well. Satisfying to gradually build up your sword army and mix and match sword parts. Also loved the little bobbing animation of your swords in the background.
Also well done for getting a good Save System working in the Jam time. I know they can be fiddly.
For improvements, I'd say the UI needs tweaking up a bit/some more consistency. I noticed that only some screens had exit buttons, and exit buttons were inconsistent in their style. Also, its quite hard to actually find the Sword parts stats, I could only see them in the Shop and combat.
The improvements are just minor points though. Fun game, congratulations!
