I think the blocking and deflecting is a really fun idea! I struggled a little bit in the beginning especially with the floating laser dudes because they would get real close to me. But it might just be me being bad at multitasking and not running further away from them. I think perhaps mapping the arrow up to jump would be a nice addition. I didn't realize this until the boss fight, but I think the shield would turn blue only a split second after I click it? A lot of the times during the relentless bullet firing by the boss I felt like I _should_ have blocked it but the game didn't detect it. Maybe some leniency frames here would be good. And it would be nice if the boss only started firing when I entered the main room! Also, cool audio, definitely kept me on edge!
