I really liked the puzzles and the core mechanic! The way the game is presented gave me major World of Goo vibes
The design is very clever, and the way in which vines can interact with water and environment feels very thought out
If I were you, I'd take this project on into a full game after the jam, maybe with improved graphics? They're really the only aspect of the game that didn't quite gel with me right, the more detailed vine does clash slightly with the more simplistic backgrounds, so that could be an area to improve later on
Other than that, like I said, I'd be fully interested in getting this if it got a commercial release! Keep it up :D
