I really like the idea of picking up as many pieces of 'weaponry' that are both your lifeline and upgrades to better shoot and defend yourself! Those red cubes were super useful for someone like me who sucks at bullet hells!
I found the audio a bit janky, in that the shooting sounds feel a bit low quality compared to the music, which distracted from it.
The colours are well chosen to make everything readable at a glance, which is super super important in bullet hells (especially for people who suck at it! looks at self)
