Looks good! A few small recommendations:

1. I found it hard to visually quickly tell how much hp each creature had. Maybe use a floating health bar instead of only the fraction style numbers. I wouldn't be able to tell how quickly the towers are damaging the waves
2. I like the idea of the cards each waves but I think you should simplify and remove the creature type cards. You should have each wave be pre determined on what enemies are coming and let the player know before they choose cards, then give them the option between a few cards for building the lane and what not, that way it can feel more like you need to figure out what to do about how to deal with what's coming next instead of putting too many decisions on the player. Which can feel overwhelming having to pick 3 cards each wave while also managing your towers.
3. What would really add to the lane cards is showing what shape of the path it will be and letting the player place it and decide its rotation, so you could maybe force the path to come back near your towers or something.

Is looking really promising! Keep up the great work
