This game and its bosses are super creative! Even though there were only 2 (If there were any other bosses, I couldn't find them) I had a lot of fun fighting them!
The first boss was really fun to fight, I instantly got drawn in with the way the fight was like a puzzle and you had to figure things out, just like in Zelda games. I'm also a Bomberman fan so that gets you extra points. I think the fight goes on for a little too long though, so maybe try giving the boss different types of bombs to throw at the player.
For the snake boss, I love how the hitbox of it basically gets smaller the more you damage it. It was a bit tricky to get used to the timing for hitting its body segments back, but once I got used to it I also had fun with the boss.
One small criticism, when you get hit, it's sort of hard to keep track of the player since the damage animation turns you completely transparent. I'd recommend just fading to partial transparency so it
I think visually the game would benefit greatly from some additional 2D lighting, I recommend looking at how to do this in Unity with the URP. It wouldn't take long and would definitely add a great atmosphere to your game.
This is probably just personal preference but I think the movement and roll speed should be a bit faster, especially when the camera zooms out because then it feels like you're moving super slow lol (but I understand it's meant to be like Zelda, so that's probably why it's that specific speed).
For a whacky setting like this, I think it'd be great to have a crazy story to go along with it, perhaps with some short cutscenes or dialogue exchanges.
Overall, this was a great entry!
