Damn bro.

I can tell a lot of work has gone into this game. It is really good, and you can feel when you've screwed up. I really like it's art and it's feel. 

Minor defects: 
Tiles are repetitive 
Many times when I had achieved 15/15 flowers, I didn't complete the level(weird bug?), maybe use >=. 
The "Start" button also does not matter, I don't think there's need for a start button. 

But overall. This is such a cool game with interesting gameplay!

Pretty good.

Simplistic Art but perfect at what it needs to do.

The UI in the tutorial part was a little weird(If you didn't know or haven't done already and you also use Unity you can select the Canves gameobject and select the scale with screen size which makes it kinda compatible with different screen sizes bigger or smaller).

and most importantly It was a complete game Unlike mine which makes it even better :)

Congrats!

A really unique take on the theme! It can take a while to get used to how the plants grown and the mechanics behind it, yet I found myself experimenting in the sandbox mode for a long time! :)
