The visuals and mechanics are super good, but in my case (because of my screen size 1920x1080) the cards took almost a third of the screen space and I couldn't click the next wave button because of that.
Also I run out of space to grow new plants very quickly, and I couldn't figure out the merging thing (probably again because the screen size).
Other than that, it's a very nice looking game and could be worked on after the jam!
