I saw your progress on this in the Discord server and it definitely caught my eye. Glad I finally got to it! Playing on keyboard does feel a little clunky, but I'm sure it is smoother with a controller. I'd be curious to see how a WASD + mouse (for aiming and attacking in 360 degrees) combo would feel.
More enemy types and variety in the tileset would be nice to see, but I think you chose wisely in terms of avoiding scope creep and having time to polish the core game. Nice work :)
