I like the game idea a lot! If this was a polished released game in the style of Slay The Spire etc. i think I would actually buy that and have a lot of fun with it. I'd wish fights would be a bit faster, but I loved the effects later enemies had, like the poison and I think you're doing a great job at showing what possiblilities you could have with this game if it had a bigger scope. I think you did really well explaining the game without much need for a tutorial. Great job!
