Well it's a weed themed farmville like game. Bold choice to have a 10 minute unskippable wait for growing plants on a demo. I think I've exhausted all I can do and am just waiting for the plants to grow.
This type of game isn't my cup of tea, but I think it's a decent implementation of this type of gameplay. I understand its for mobile, so I'd maybe add a big back button so the player can easily get out of menus. I struggled a while to realize to back out of the phone was to click the home button.
Nice art. Good luck!
