i watched your progress in the jam channel (#tech) and you pulled it all together quite nicely! the player speed is just right for corralling the swarm while remaining in danger. good call to go the doomy shotgun route without reloading. please add a double barrel (super shotgun) for V2.0 =)
i was surprisingly able to play this in the browser on an M2 MacBook, but the final boss was my trackpad. will give it another go with a mouse later!
