Very cool idea. Having players start out weaponless and dying is a fun and creative way to introduce them to the gameplay loop. I feel like this game could really shine if some more time was put into the visual communication/UX side of things. Overall great job!

My biggest issue with the game was that sometimes I could not see what was going on. That also was not helped by there being multiple UI elements that did not properly tell me what they were for. My suggestion would be:
add icons for health, weapons and the shield, and implement some more visible particles/VFX from the weapons themselves and maybe some blood splatters upon hitting enemies.
