This is a promotional giveaway for a solo dev's first puzzle game, Regrowth.

Regrowth is a puzzle game where you race against time to save islands from sinking.
Use plants and animals, collect and channel water... However, only with strategy and optimisation can you solve all the levels.
Will you be able to save the earthen realm?

If you are interested, you can visit the Store Page for the trailer, gifs, screenshots or to wishlist the game, see the development videos, or follow the dev on Twitter.

I was one of the translators and can wholeheartedly recommend the game :)
