Great idea, I don't think I've seen another entry like this one. Nice play on the theme. Good art and music.
Sometimes, the text would overflow the container, so I couldn't read it. The cards wouldn't always be detected when placed on the monster, which was frustrating given there was a timer. I'm not sure if it was a game design decision, but there seemed to be too little info to make decisions. As a simple example, height would often be mentioned, but there was no relevant data. Maybe I missed it?
Great entry overall though. Well done.
