What an incredible game ! There is so much potential!
Some random feedback:
- I never used the scanners, it was faster to browse the map with the mouse. Maybe being able to switch between views faster, or combine the 3 views into one would be a good addition
- I noticed that I spent more time looking at the scanner at the bottom right rather than the map which is a shame given the magnificent artwork you did
- a small z-ordering problem: when you put plants behind a tree they appear in front
- at the end I tended to click everywhere without really paying attention to the scanner, it could be interesting to add a seed rarity system. Maybe the robot should collect them from the plants so that their quantity is limited, and we develop more sophisticated plants as we go along
In any case it remains an incredible work in 3 days, congratulations! (it could totally be extended into a full game :D)
