Music - goes really well with the rest
Art - Good, less is more, however maybe it's just me but it'd be nice if the NPC animations were a bit more obvious so I could prepare earlier to block. I was just mashing LMB then RMG. But style wise - you nailed the arcade games feel!
I'm not a fan of mashing buttons so this was a bit tiring for me personally. However, I liked the time steal mechanics.
The UI was very clear, tutorial easy to understand and not bloated with information.
It is definitely on theme with the game jam. It feels like a memorable game.
Good job and good luck!
