Cube hell

[wooden talon]

Hello guys!
I'm working on a small 2d bullet hell game called Cube hell, inspired by some cuphead levels.
I'm new to unity and C#, so i'd really appreciate any feedback on the game. the game is not finished yet, but i'd say it's about 65% complete.
I feel like something is missing, but i can't quite figure out what.

I've attached a short gameplay video and and some images to show the current state of the game.

Any feedback or suggestions are very welcome!
Feel free to be honest, I'm here to learn.

I'm still a beginner too, but in my opinion I felt like the course of attacks is repeated and quite predictable, I would suggest working on the enemy's AI a bit more while also making it quite easier to dodge them too ( I saw u struggling a bit in the gameplay ), and maybe the shop too? adding more upgrades would definitely add more content and goals to the game.
Overall I love the idea and I wish u the best :>
