First of all, thank you for sharing such a fun game.

The very first thing that came to my mind when I started playing was Zelda II: The Adventure of Link. I couldn't help but smile at such a faithful homage. (It's also one of my favorite NES games, and I've spent countless hours playing it.)

That said, the graphics and music are fantastic, and you've turned the inspiration into a game with its own unique charm. I'm really impressed by how much content you managed to create in such a short amount of time.

Due to time constraints, I stopped after defeating the Vampire Queen, but I'm looking forward to seeing what adventures this adorable little rabbit has ahead.

A few things stood out to me while playing. Collecting carrots by repeatedly defeating the same enemies started to feel a bit repetitive. (If there's a more efficient way to gather them, then please ignore this! Alternatively, a progression system such as leveling up might make the repetition feel more rewarding.)

Also, early in the game, I exited the cave from the lower exit without having the key, and I wasn't able to re-enter the cave afterward. I'm not sure if this is intended or a bug, but I had to restart from the beginning.

As for the Vampire Queen, I eventually defeated her while dodging her attacks, but I wasn't entirely sure what the actual victory condition was.

Even in its current state, this is already a wonderful game. With a little more polish, I think it has the potential to become an even more memorable one.

Thank you again for making and sharing it!

Cute character sprites and good music! There seems to be a stray pixel a bit to the left of the rabbit when jumping and crouching while facing right during fights in the cave.
