I really like the look of this game, and I adore the cover image of the ivy growing out of the keyboard.
There is actually some really interesting strategy when you get multiple new buds spawning, since you don't control which one you start from next. I ended up waiting so that they would all align in relatively good directions before i started growing again. If one direction got out of hand, i could always do a short press to try and reset to control my direction better, but then i had one less key to use! I think that made for a pretty interesting balance of strategy, even if it was pretty much always worth it to me to lose a key to regain control.
Really liked it, well done!
