This reminds me of the classic Atari Sword Quest games. I don't know if the game is still a prototype, but the build that I just played is riddled with bugs. I was able to not die and scale up walls infinitely, most paths lead to nothing, there was a room that broke the game and the audio from your projectile loops over and over.
I didn't encounter a single enemy but I was able to find a simple line puzzle. I really like the character animation, given how minimal it is. I wish there was a solid build of this up cause I'd love to explore more of the game.
