This demo seems quite polished, but oviosly not finished Im not sure where exactly you intend to go with this but it has great potential
One small thing tho, the timing for the burst attack is very tight and not relyable enough. I would recomend for it to trigger whenever one wheapon is charging up and you press the button for the other one. this way its always a quick backup option in case an enimy gets a bit to cosy with you.
Sorry for my potentialy bad english its not my native language
