Fun game!
Couple of nitpicks..
- I'm not a fan of payment requests for jam games (but that might just be me)
- It seems overly large for the content (nearly 200MB?) (doesn't affect gameplay, just an observation)
- Those instructions really need to be in the game. I never would have guessed that you needed the cloud to water the fields. (again, a minor nitpick, since the instructions are available on the itch page for those who care to look.)
All that said, I really liked the papercraft art style. I also thought that it was a nice riff on lane-defense games, allowing you to place your defenses anywhere. Given that plants vs zombies is the most popular in this genre, I'm a bit surprised you also went with plants.
Good game!
