Bolt Bucket has a cool idea at its core. The new player experience could use some smoothing out — I also encountered a bug where rerolling the shop caused my weapon to vanish.
The autobattling mechanic is solid and seems well-balanced, though the pacing felt slow. A 2X speed button would help tremendously, or even an active skill to give the player something to do during fights.
UI, SFX, and music are all well done. The biggest visual drawback is that parts lack basic distinguishing art, making it hard to tell things apart at a glance.
Overall, an interesting entry that fits the jam theme nicely.
