This TD x Card game is pretty fun! It was clear and easy to play, and controlled well overall. It did seem like the stage was a bit long. I eventually lost when I cranked up the speed, but didn't keep up with the defense to match.
The art is good, and the character sprites in this game are quite adorable!
I'd love to see a story or goal to keep me wanting to play more. This isn't a big issue since it's a jam game... I don't expect a fleshed out world or story, but that is something that would help me want to keep going if this was a full game.
Overall, this is great work! Keep it up. :)
