I'm not a huge fan of card games, so I was a bit concerned going into this that it might just not be my thing no matter how good it was. I couldn't have been more wrong though, this got me hooked almost instantly! I can honestly see myself coming back to this fairly frequently.
The only things that it's missing are some kind of online or local multiplayer (which, granted, is a bit much to ask of a jam game), and some kind of in game preview of what cards are going to do (other than the descriptions). I found out the hard way that seedlings are in fact the 'deployed' plants that can attack and defend and not the plants currently being grown when I used a blight card and saw my two turn victory get thrown into the discard pile. Some visual cue of what the blight was going to do would have prevented that.
