Suggestions: You should add a way to reset in the third room with the wind. I soft-locked myself by growing a platform on the ground to get up, but the wind is too strong.
There is a way to reset the level! In the beginning of the game, when you first pick up the seedling, the text says you can reset the level with Z. I can make it clearer that you can reset tho, as it is embedded in a block of text.
