To start off, I'm genuinely impressed by your spin on the genre and I honestly think that a creative twist like this is very much welcome in this theme, breathing new (plant) life into it. I didn't expect myself to get this invested and addicted so fast but it was such a relaxing and quirky game. Love the nature theme and the mechanics are amusingly logical and fun, complimented by the soothing soundtrack.
I have one suggestion though. The sprites of reddishbrown roots in marsh color ground are kind of hard to see. I love the colorschemes of both zones but in the first one I'd consider at least a bit darker ground at the root level and beneath just for that reason
It's amazing how much content you managed to put in a game jam project while remaining fresh and interesting to the end of this demo. It was honestly a lovely experience and I'd love to see your next works.
Well done and cheers!
