Interesting little simulation game though a bit slow. The spreading mechanic is really cool and I hope you expand upon it.
I feel like there should be fewer guards in the first wall to let players build up more and quicker. Maybe give all creep the ability to do a little bit of damage rather than having to wait until the Flower ability, which is pretty late. I feel there is a need for a different control scheme, it’s too click intensive.
I ended up putting the game at times 4 speed to spread faster and overwhelm a section before moving to the next section. The attacking enemies attack a bit too much from the start, maybe have guards attack once or twice in a day and then have to go back to their house to rest. Sometimes a single guard would decimate a lot of Root so fast.
Might want to add a greenhouse direction next to where the player starts at to show the player what an object is rather than only having the explanation in Info.
