Very well thought out and put together game and bizarrely addictive! I really enjoyed the extra random challenges throughout that could set you back if you hadn't planned properly and the changing around of the water carriers to ensure a constant supply kept the ol noggin whirring. Personally, once I got going, I found it a bit too easy towards the end on Normal but glad there are other difficulties to try. Incredibly informative, you can really tell a lot of work was put into this - research and programming wise- and that it was a labour of love. Very enjoyable - thank you!
