Luck and permanent death are not a good mixture for a game. Many parts of the game rely on platforming skills and figuring out how to progress (you can get through a lot more than one might expect without using dead bodies), but the parts that require there to be bodies for you to progress is not only blatantly unfair (your game basically already points this out), it is also undermined by the fact that those sacrificed bodies will disappear at some point or only some dead player bodies are generated for each run. I managed to play the game multiple times and have yet to beat it partly because of that last room that requires multiple sacrifices to spawn in a path like formation for anyone to win. While I'm sure I could beat the game at some point, it just isn't worth it. If I fail, I'd like it to be from my own shortcomings as a gamer, not because 10 other gamers didn't get to the same part and have to die unfairly.
This is definitely an interesting experiment to say the least. It probably won't garner mass appeal as it incorporates aspects of life that people play video games to get away from, not to experience them in a 2D format. Regardless, I enjoyed the platforming challenges and the smooth feel of the controls and the graphics were pretty good as well. I wish you luck in your future creations.
