The game definitely has a lot of potential and I really love the ability to change bob into different versions to progress exponentially. It's really juicy as well with all the small animations. the art is also really great being consistent across the level and the UI. I'm not getting any sound but wish it did have some as this would make the juice even more effective.
This is a really polished experience overall. It could do with a small tutorial just to get the player started as I had to mess around a bit before I understood the game loop. Also I killed bob and it just went black rather than sending me back to the menu or restarting the level. Also there isn't much risk to the loop, players aren't limited in any way by the cards and its pretty easy to keep all the bobs alive since you can stack the food.
