Nice game. I really like this kind of game. For an advice. It's so pain when I need to go back to start room everytime after I killed enemy. I hope you will have an update for this.
Instead, could you make the respawning thing a toggle? Just so people can decide to make the game harder or easier for themselves. I personally like the idea of a respawning mechanic, another game I like on PlayStation has something similar to that and it just adds a layer of strategy.
