Thanks for playing. People have problems understanding how to play it :) I didn't have time to make proper tutorial during the jam.
I have seen in the video that you had problems with teleporter. X - is used to place it and pressed second time teleports player to its location. C is used to clear teleport so you can place it in different place.
Second thing is genome you have created. You would get better results if you had placed dots in forward and root boxes for all directions in the beginning.
Third that grey arrow points you to the "Flower" which after unlocking will let you level up your genome.
2 dots to forward in all 4 directions UP DW LT RT
3 dots to root in all 4 directions
That will allow you to grow bigger trees and gather more dots for further experiments with a genome.
