Looks like a nice 2D platformer. Graphics were good, along with sound design. I had a habit of hitting the up key along with the jump key, and most of the time the jump was ignored in favour of the camera moving up. Think that jump should always be triggered in such cases. Fell into the pit area, couldn't play on from there. Think maybe enemies need more of a stun. FYI I downloaded the windows exe as the web version just stuttered too much -- noticed this with Godot games in particular. I would have also liked the game to launch in fullscreen mode, as it was tiny when windowed.

The visual and audio style here were excellent! However, there were some core mechanics that were a bit too clunky to enjoy the experience. Here's what happened for me:

1. First play through on a new game, I had the dialogue text appear and say "And now a final third attack" or something.

2. I refreshed the game and selected "continue". That's when a new text box appeared saying "You should not be seeing this text." I laughed.

3. I started a new game, killed all the enemies in Room 1, got the secondary attack, made it to room 2, then fell to my death. Unfortunately, I didn't die... I just kept falling and was softlocked. I had to restart the game again. After reaching there a second time and falling again, I gave up :/

4. Aside the buggy behaviors on game flow described above, the main recommendation I have for you to fix is the feeling of the combat. Right now, your attack is SLOW. It's so slow that if you were to start attacking after an enemy, they're guaranteed to hit you first. Which btw, the enemies have almost no "tell" indicating when their attack is going to happen, it's nearly instant and not really interesting to play against. More important than any of the other feedback is this one: DO NOT LET THE ENEMY'S ATTACK CANCEL YOUR SLOW-TO-USE ATTACK. That was infuriating. I would essentially be caught in a loop of trying to attack and not being able to because the enemy just kept zapping me indefinitely and revoking all control from the player... Spamming the attack button eventually worked, but it felt terrible. Designing an enjoyable attack system is tough. The ones that work best are typically the highly responsive ones. If you want a game based on long buildups for the attack, then make the enemies and environment more conducive to that playstyle.

I like the design a lot  lighting looks very good. The fighting system is very slow, and not so good I think. - Music made a very nice mood!

I have fallen down a pit yet I didn't die nor reset and was stuck there forever and ever

The 2D lights are super cool and make the atmosphere of the game kinda spooky :D The attack has a longer than expected delay, so it took a bit of time to get used to the windup time.  It was fun exploring! Awesome job~ Keep working on it, it's a great start!
