Just had a playthrough and the game was pretty good!
The death mechanic was a really cool mechanic and was interesting to play around with.
As others most likely have already said, the movement in the game just felt a bit unresponsive at times, or a bit floaty, but I know you're releasing a patch to fix some of those problems.
The sprites and art individually were pretty good, but when put all together they just didn't match the best imo, like the saturation and bright colors on the gui bars compared to the more toned down colors on the world foreground stuff, or the style and some black outlines on the main character, compared to the style of the foreground also with no black outlines.
If you're gonna update this game even more, I'd also suggest adding some more feedback whenever you die, especially since that's apart of the game's main mechanic.
I also have one last idea, not sure how well it would actually be in execution but it's just an idea you could look into. Each corpse after each death could possibly have a deterioration process or something so they wouldn't stay there forever. I feel like this could add to the game's difficulty a little and make it a bit more challenging and interesting to play, as then you'd need to be faster and make it in time before some of your bodies vanish, it would probably also fix a few future issues with the game having too many bodies at once blocking something. Like I said, I'm not sure how good it would actually be but it's just something you can try.
Overall the game was good and you did a great job!
