Frustrating (and probably abandoned) game.I'm feeling insulted.
After having mastered it a few times (including an under 60 turns winning game 
using the same or similar parameters on the same levels, I've never been able to replicate or even approach it - even after a 500 turns test) I'm forced to conclude that winning or losing mostly doesn't depend on my efforts but on the game's poorly managed randomness - and if we take into account the unobtainable ('coz bugged) medals, it's just...
... sad, it looked so funny & promising. I've read the dev writing about the tech he used (Unity) that 'this game is 4 years old xD'. Well we're a large bunch who are still playing 20 to 40 years old games built on clumsy and obsolete tech.
4/5 for the promising concept, .5/5 for the deceptive result. In the end, .5/5.
PS: about mastering a game (which can't happen here anyway since major bugs have never been fixed) if there's too much randomness there's no mastering at all and the player just owns a gilding arsehole.
