Fantastic idea! I thought I could just build walls all around my turtles and have an infinite supply but it was way too hard trying to get that to work. Maybe somebody smarter than me can figure it out. That being said the idea is super cool. It's like a tower defense on crack. I feel like if you go back to this, you should add some sort of goal the player is building up to. I'm not really a person that plays a lot of resource management games and its because usually I need to make my own goals, but I'm bad at that, so a little something to help guide the player will be great. Fantastic game!
