Here is my feedback for your game too as well.
Overall this was a nice short puzzle game. I do wish I had known what influenced the ending I got though while playing the game. Some way to know that, or even a message about it after you get the ending to clue in the player would help a lot. Also I had a hard time seeing the plants in the fog so I lost more health than I should have.
As for suggestions: I kinda found myself wishing for a way to heal HP occasionally. Could make it rare as you do have the multiple lives too. Could even hide it in a secret. Or...did you and I just never found it?
Overall though it was nice and short and a pretty enjoyable game, just needed some small improvements here and there. Good job on getting to the finals too in the IGMC!
