First of all, the graphics are gorgeous! Everything looked so smooth.
At some point I got stuck, I think it was the same issue Allison Liem had.
The plant drawing mechanic was very innovative and fun, though I missed the words often by a few pixels as my cursor got outside the game window (I think it would've worked better if I played in full screen...).
I also had a bit of a hard time reading, because it was a lot of text and it wiggled around. Would have loved to have an option to turn off the text moving (though it looked great to be honest :D).
Last but not least, the sound was very relaxing and set a great atmosphere!
All in all a great entry. Well done!
