Nice concept and interesting pixelized 8-bit graphic. But current game version has a weird bug. Purchasing scientific upgrade that should automatically sell energy in fact does nothing. You still have to boringly press power-to-cash button and convert it manually. Game progresses quickly to the level where energy production is high (that's the whole idea why auto-sell upgrade is one of the first) the whole game experience turns into pressing power-to-cash button every second and nothing more.

Greedy dev. Changed from 4 star to 2. Played like 2 years ago, threw some money at it, pretty enjoyable game. This time around I'm not buying any upgrades and WOW this game is very demanding. Between the constant optional ads that you dismiss and pop back up within the next minute or two, you'll eventually be hit by the sneaky "wait until you're invested then pay to progress" move. At one point you'll have to delete eeeverything, replace them with research centres and wait for 2 days. REALLY!?

I would give this 5 stars... However, the fact is that after 2 days by which point I had gotten to nuclear power, it took me a week to get to the next phase of which was thermal. The unbalance for different stages is outstanding and the grind is off the scale. This means that you normally forget about the game after a while and it gets reasonably boring. I suggest as a way to fix this you could add a leveling system which gives you money. Except for this it's a great game worth 4 stars.
