To be honest, It’s actually fun with lots of different level scenes. But small issues though. First, in one scene I fell into the water but didn’t die. I was stuck underwater with no way to climb out and had to restart the game. Second, the boss is way too hard. The boss’s skill design itself is solid — you clearly put a lot of thought into it. But its attacks barely pause at all. I can only keep dodging and never get an opening to strike. I’ve tried dozens of times and still can’t beat it. I don’t know how much more content comes after, but I’m totally stuck on this boss.

Also, the dash feels a bit underwhelming. There’s no invincibility frame or something while dashing, so I keep dashing into damage and killing myself lol.

Still, it’s a really solid try. Keep going!

The controls are pretty nice and the game is responsive! Though, maybe it is way too smooth to be in the spirit of a gameboy game.
Aside from that, I couldn't hear the music well, and I don't think it was looping...
The level design is pretty nice though!

Hey, nice work on the level design! It stays varied and never gets monotonous.
I haven't been able to complete the game, as the boss kept killing me. Maybe I'm missing something crucial about the combat system.
Just a little note on shooting upward: it feels a bit clunky because you're forced to jump to do it.
Anyway, good job!
