Hello, I think this game is pretty good. The premise is simple, but good The game is easy to understand but hard to master. The only thing that is bad is the issues the game has. And still, the creator listens to the community and fixes the issues the players give him. Overall, a pretty good game.

honestly, i think this is fun.
my only complaint is that i'm having trouble understanding what's killing me half the time.

specifically, aside from the "blasters" lasers which instantly kill you, everything else seems to deal damage at random.
sometime i'd take 3 and some other time i'd take 20 from the same attack.

the exact pointer hitbox is also somewhat unclear, as sometimes i get hit even though it feels like i shouldn't. though that must be a visual problem and not the game's fault.

another minor issue i have is the "green floor" at the bottom of the screen.
it's a perfectly serviceable play area, so you can move there normally, but due to the color of the bullets being yellow it's difficult to use, and it also adds nothing to the gameplay.
personally, i'd be fine with it not being there at all and only having a solid blue background

tbh i think most of the "difficulty" comes from the fact that you can basically hit the boss only during its blasters attacks (when it's completely still), while every other attack pattern either doesn't have a hitbox to attack, or the movement tracking makes it so it's impossible to stay in line with the boss without getting hit in the process.
considering the patterns are picked randomly, it all comes down to how many blasters attacks in a row you can get before all the other patterns kill you

my most hated pattern is the bullet circle because it triggers instantly regardless of the previous pattern and each bullet deals about 20 damage, so if you're locked in the middle from the previous pattern for whatever reason, you're pretty much dead.
the bullets themselves are really big, and staying near the border also kills you, so it's really difficult to dodge as well (for me)

edit: i hate bullet circle so much it does so much damage and when i die to it i'm told i died "due to touching the screen" regardless. it's like it's mocking me

Edit: The new update definitely improved the game. For it being your first game it is pretty fun. Especially the attack I criticized at first is now extremely satisfying and fair good job.
I would make the damage ups more frequent.

Rage games are not supposed to be unfair. The one pattern where the bullets come from all directions is impossible to do no hit, why not just make the bullets slower? That would make the pattern doable but still really hard. The lasers might spawn in positions where there is no way out and you will die. Make it so you can hold the left mouse button to shoot.

Was a bit confused, would highly advise changing the music as copyrighted music isnt allowed, otherwise, perhaps make it a bit more clearer by telegraphing what's gonna happen for an attack

Very fun and creative! Just needs some polish
