First of all, congrats on finishing a game for your first ever gamejam! It's a fun little concept, being able to place trees on a planet and grow an ecosystem. Though I found it quite difficult to not fail the game. I think the problem was that trees drain water quite quickly, much faster than I was able to water them all. Maybe if you reduce the drain time the game will become easier. Thanks for making a game for the jam, hope you had fun!
