Nice demo. Took me about 5 hours or so to get everything unlocked, but I'm sure I could have done it faster if I were being more efficient. The tech tree gave me enough to think about in terms of the order I unlocked things that it felt like there were meaningful choices, instead of just buying whatever the next cheapest thing was. So, a surprising amount of depth for people who feel like optimizing.
It was a little confusing why I had negative money sometimes, but I eventually figured that out. Maybe that could be explained somewhere?
Overall, cool game.
