This is just a blast!
The first words to come out of my mind while seeing the menu, and realising the light follows my cursor, and this is a quote: "Yooo this is DOOOOOOPE". The shrimp battle is an absolute jam, and apropriatelly for a bullet hell, it feels properly crowded. My goodness, the visuals are amazing. The lighting is on point, the anticipation/announcing/warning shapes leave just enough time (although at times they are a bit hard to see because of the intense flashing and low contrast against the background). The transitions and effects are simply glorious.
Main point of criticism: healthbar? I had no idea if I was at pretty much full HP, or on the absolute brink of death. Another thing - you can walljump and it's reaaaally useful, but there are no... walls in the visual design of the game, so I didn't realize I could jump off of invisible walls. Another thing that would be really handy with this level of intensity would be having some sort of invincibility frames after being hit, because many, many times I just fell into a big projectile and got melted in less than a second.
