Pokemon meets Slay the Spire??

I've been working on a little side project and was looking for some feedback on it - I'm just really proud of it as I've never done anything like this before.

It's a pokemon deckbuilding game inspired by slay the spire - what sort of things do you think I could add? I'd love some critique :)

Here's a couple minutes of gameplay!
