Good work!)
Took me a while to understand the mechanics. I didn't realise you had to sacrifice a building to power the other buildings, but once I understood that it made sense how to play. I like the keyboard control stuff, but it's awkward to play. This could work really well on a touchscreen, and you could have different shaped layouts that aren't tied to a keyboard. Different shapes would require different techniques for powering awkwardly located structures.
Great job!
the only issue is it took me a while to figure out the controls and especially how to «activate» the buildings on the sides. the logic behind that wasn't obvious for me.
nice entry!
Was hard to understand at the beginning, and also a bit slow-paced at the start, but it is fun playing it and also the graphics are great.
The game looks good and polished, great work :)
Would love to play a fledged out version of this - good job!
