It started very promising, but there are a lot of unclear things, such as the On/Off of the buildings, it is never specified how does that even work, thus building the required things still didn't produce me anything at all.
I can tell there was a lot of effort put into this and i'd love to play the whole thing, but not being able to beat just one stage because of lack of instruction makes it very unattractive.
I can see this as a great play, it does not need polishing, it needs to fix its basics.
