It's just browser-old-flash-game-like clicker - only difference is that it's looks better (more polished). And like some flash clickers from past - it turns low-spec PC into jet engine. Which is suspicious, considering system requirements of this game. My GT 1030, which can run games like Metro 2033 etc. smoothly, has 100% use, even in main menu of this game. Very suspicious. To be honest - playing this game was quite OK in first 5 minutes so it deserves +2 stars added to final rating. This game is free and that's biggest pro of this game.
