This was pretty fun! I think the hitbox was a bit too big and I sometimes got into a spot I couldn't really escape from, but other than that, it was a fun game. Good job!

Ah, so much fun! I read your comment below about the hitbox for the PC, but I think you could go even smaller here to give the player more opportunities to survive those close calls and live to tell the tale. I gave it a few goes, but, unfortunately, it looks like it's dragon egg omelette for dinner tonight. Thanks for making and sharing your game!

TAKE THAT, YOU WIZARD!  Now I can have Roasted Wizard for dinner!  My final score was 460. It took me only three tries to win! :)  BTW, you are right, the hit box for the dragon IS small.  It is not as difficult to dodge the attacks as one might think.

I like the changing backgrounds as you make progress.  I like that the key is used to unlock a new level!

I wish you could have move forward or backwards a bit. That would have dodging a bit easier.

This showed up as an error in the javascript when I booted it up on Firefox:

draw() { ctx.drawImage(this.image, this.frameWidth * this.frame, 0, this.frameWidth, this.frameHeight, this.x, this.y, this.width, this.height) }

As a fellow js coder, I salute you for your efforts!  You have done an outstanding job! You are a contender for the Kuro Bread Award!

Darn I couldn't get to the tower, the hitboxes were a bit too big and it was difficult! the dragon animations were cool and i did get a great sense of speed from everything!
