I really liked this a lot while it lasted; unfortunately the two times I played it ended in a crash. The game itself never closed and I could still move around/hear sound effects, but the image was frozen. As for the game itself: it's kind of hard to see around walls that you create, and the UI is a little bit hard to understand, but once I got everything it was very fun to play. I'd say you hit your marks, great work and keep it up! I'd love to see this develop further!
