I’m personally interested in this kind of game, and I think you’ve taken a really good approach! It’s well-balanced, has nice colors and a great art style, and the rules are clear.
I’d suggest adding a sound slider, or at least some background music. Right now, after a period of silence, the sound effects can feel a bit too loud.
And again, I want to say something about the colors and style – I’m not usually a big fan of pixel fonts because they can be hard to read on larger screens, but you did it really well here!
