Really unique idea! But the difficulty scaled up way to quickly! My first encounter with the dummy didn't lead me to believe that the enemies would be shooting back. But once I figured that out I was able to defeat the giant spider. Next up was a mimic. Tried at least a dozen times, and probably a bunch more. However I never had a chance to "run away" and just had to keep trying again at the end of every loss. The novelty and enjoyment quickly faded at that point. I think there is a lot of promise here if only the difficulty didn't from nothing to 100% almost instantly and/or you had a chance to run away from more difficult fights after a loss. With that simple change I think you'd have a really fun game then.
