I liked the concept of growing emojis!
Nice aesthetic, very nostalgic style!
My main feedback is the minigames were a bit grindy, like waiting for a raindrop to fall or clicking plant, then square, then water, then square, etc. Or maybe instead of grindy I'd say patience demanding, similar to unskippable cutscenes, like where if you aren't already invested there isn't a lot of incentive to do it more than once or twice. My recommendation for this would be to set something that can run without constant focus, like doing water supply in the style of that old Win 3.1 game "Pipe Dream," but adding new outputs as upgrades for the player to optimize as the demand from the emojis grows.
The structure for something really cool is in place here, I think with some more focus on the the progression or gameplay impact of the emojis it would be alot of fun!
Good work!
