dunno why someone below mentioned lack of audio, the game sounds great! I felt that there wasn't really much info, that there could have been more ways to tell that could have each been more subtle. Something to consider is the game's meta, aka the most effective tactic available, which at the moment seems to be: "if you see a bloody room, backtrack til you find a non-bloody room, then explore from there". There is a lot of potential here to improve upon that loop, so you need to be smarter or do more varied gameplay. This reminds me a bit of high stakes, which gives you a subtle amount of information to solve a really tricky problem. I also think the movement in your game could be faster, especially with rooms you've already visited. With the meta mentioned earlier, it can be a bit slow to get back to those old rooms.
But beyond all that, it's a very neat game, you've done so damn good with that death animation, like hot damn those monsters are cool. And being able to zoom in / out is some nice polish. Your art and audio are both outstanding, the style is super unique!
