I found it really tough to beat any of the bosses but i kept getting so close that id just 'have one more go'
I thought the use of the theme was well done and each of the bosses had its own feel and energy. Picking up the ammo and health was a fun twist, though i feel like maybe it could be a bit more forgiving,
I liked the boss's had differnt phases as it meant i had to switch it up as i progressed throuhg the fight. It kept the fights engaging and fun.
I thought this was a neat mechnic execute well. great job
