Reactor Idle Tycoon

I have completed all researches and opened all islands (except last of course) without paying anything in a few weeks. I had a good time playing this game which graphics is awesome. As side note I would mention that cost to upgrade for any power burner after coal burner is absurdly high, it is cheaper to develop and buy next generation of heat source. Also I didn't manage to use dark energy generator because it requires insanely priced upgrade even for ultra generator. It'a pity that progress goes four time slower when app is closed, game center looks broken too - it can't process such big numbers. But overall it is great game and in the end I bought an upgrade from dragon for real money just to support the developer. Thank you for the game and keep up the good work!

UPDATE: When I wrote my review before I hadn't even realized that the game would let you prestige to additional runs. I'm now through 16 complete prestige runs. (I put the game down for months, though, after the first few.) A run now takes me less than 20 minutes. I still think the game is great, although progression is a bit odd at my level. (I only ever build two types of the offices and generators. I don't bother unlocking all of the islands because it just takes too long. I use at most three types of producers and use windmills until I place tokamaks.) The only additional thing that's bugged me is that building and demolishing so many buildings gets tedious. I really wish there was a "paint bucket"-style tool to fill/clear whole continents. I'm at the end: I've completed all research and I'm getting close to building dark energy reactors. I spent $0 on this game, though I've certainly watched a ton of ads. The game is compelling and one of the most interesting things was the need to constantly switch up the composition of your buildings as the phase of development changed at each research level. (Multiple generators per reactor to multiple reactors per generator.) Needless to say, I found the IAPs to be unnecessary for progress. My biggest heartbreak with the game was, in fact, the ads. Good news: they aren't intrusive and they're only going to pop up when you want the bonus they'll provide (which, in this case, you'll want basically always). Bad news: they're 'rude' and stupid at the same time. Your device is muted? They still play at full volume. (To add to the fun, they sometimes don't even have a mute button in the ad.) You're holding your device in portrait? Some will leave your screen black (and play noisily) until you turn your device. You're going to love this game and hate the ads.

I’ve enjoyed the game and thoroughly like that the ads are optional for benefit; however, I do find parts of it very annoying. First, it would be nice to have a way to upgrade buildings without having to delete them and rebuild them. This can be a very tedious, time consuming process, especially as the map gets bigger. Second, the removal of trees and mountains, for the most part, is pointless. You can only click each one once an hour and it takes four clicks to remove one. You can easily finish the game well before you have removed enough of each to be noticeable, and they get reset when you prestige. There has got to be a better option. Third, fix the minor bugs. There are many times that watching an ad results in an error. If the ad is for a bonus, when the game is open, you have to watch another ad to get the bonus, but if the ad is to double you away-from-game bonus, you get an error and miss out on the bonus. Also, there are times when prior tree/mountain clicks are wiped out when the game is open the next time.
