This is a great game! I like that you get to keep the upgrades you got even after dying it ensures that everyone can finish the game at some point. That being said I still couldn't make it to the treasure room. I thought I nearly made it to the end and got a little excited because of which I forgot to heal and died which then made me rage quit :) but the game is still really good i will comeback to finish it when i have calmed down a bit.
edit- I came back to complete the game and my progress was actually saved! I didn't expect that, I was able to finish the pretty fast because of that!
