Honestly, not a bad start at all. BE in pixel art form is one of my favorites. :)
I do wish I could choose where to direct the growth, but that's just because I'm not particularly into AE. Anyways...
The minigames are pretty tough. I eventually figured out how to at least complete most, but I still can't complete them consistently. I haven't even beaten the plant minigame once yet. A difficulty slider to adjust the spawn\tick rate or win conditions to make games slightly more balanced could work to help out those who are looking to experience more of the content instead of failing the minigames over and over till one pops up that they can complete.
And of course... BIGGER BOOBA! :D
