I liked the way you handle dual purpose here. It feels a bit stiff though, I think partially because the enemy fire rate is too fast at the moment and/or their movement speed is just a bit fast. Tweaking the fire rate might help more though. I couldn't figure out how to absorb the bullets, (blocking only deflected them as far as i know) but overall, pretty cool idea.
Thanks for playing! At the moment to absorb the bullet you would need to take a hit ie point the shield away, but you'll sustain damage that way. Am thinking of changing this mechanic as its not very intuitive and seems to be annoying/un-fun. Tweaking the game to be easier as well.
