Hello, good and fun game so far, I liked playing it a lot, here's some feedback in random order.
after I jump, and hold sweep in air, it doesn't start sweeping when I land.
bullets are drawn on top of the black screen after game over.
you should set holding sweep button to be as fast as smashing it, everyone will externally set their controls to automatically rapid sweep anyways.
hitbox should always be visible at all times, maybe lower it under the face or something even if it covers your art.
showing the remaining dusts is good feature
test adding bullet sealing when next/over enemies,
it would make them more fair,
dodging while pointblanking can be fun, but you might end up designing patterns that dont work both close and far or add gaps where you would kill them having no dodging anyways.
first stage should have way less dust or have way more bullets or maybe just remove the stage.
when falling from bottom to top of screen, add more i-frames after you land,
even if the skill is to time the landing between patterns, it's not fun getting hit for it.
add i-frames after you get out of bird portal, as player can't get instantly hit,
also longer platform when coming out of the last bird portal next to spikes as I kept falling into spikes when spawning.
orange arrows and bullets blend in too much with the orange background, I would change them to different color. I didnt first see the teleport spawns, they might need more communication, maybe draw a line from old to new location during teleportation.
after bombing the stars should suck into you,
it's not fun to manually collect them and adds no challenge.
it feels awful when you miss 90% of the stars every time you bomb, because you can never reach most of them.
try keeping the game going during bombs for better spacing,
maybe keep spawning bullets or even cancelling new bullets into more stars during the bomb. platforms should move during bomb too.
sweeping and grazing could use something more mechanically and scoring wise,
maybe the more score you get the more sands you sweep with one sweep,
or maybe grazing charges a charge bar for a wind blast that clears an area around you,
maybe you can launch enemies to sweep the ground with them, idk stuff like that.
anyways, it's a good and fun game even as is, dodging was fun after I got used to character's movement, jumping felt a bit floaty at first.
I'd like a ducking move where I lower my hitbox to dodge straight vertical patterns.
most fun stages were ones with constant patterns, they had constant spacing and easier to read and dodge patterns without any pauses. with longer pauses they could show before and when the next pattern is coming out, but the pattern that comes out will still be abstract without seeing the constant pattern, else it has less variations.
art is very cute and charming and fits together well, music is good and fitting even if its not super actiony.
theme is good and creative too, maybe stuff like bird portals etc seem a bit random and could fit the library theme and background more, but they are good as is too.
great work on the game so far.
