It's a cool concept, but all in all not a very interesting game. Most of the game was holding down a button and hoping to find plants, but I understand that procedural generation can take a lot of time to make (I've used it in a game jam submission before too, and boy did it take a while!)
That being said there's still a lot to like about the game. The sound design is neat, and the plants system did keep the game from being boring. The compass tool and the day/night cycle are also very cool additions! I love how the cycle affects the gameplay too and isn't just for show (but even if it was that'd still be a welcome addition!)
It's a cool game, just needs more variety. Well done!
