I have 2 suggestions revolving around the tripod, I like the design, but could you refine it a little and give it a better walking look. And 2, could you possibly add a harvesting variant of the tripod too, I'd really like to see if you can try and do those 2 things. I really like the game btw, it's almost as awesome as Team Greens war of the worlds game, keep it up!
Edit: I forgot to ask, will there be red weeds?
