It is a fun concept, I will say. But Gamsy is also correct about everything else. The balance/scaling/achievements are WAYYYY off to the point of silliness.
With that in mind, once you add more to the prestige system (like quite a lot more) it could become a solid game. Again, very solid/fun concept. Just lacks balance in a major way. Especially when one of the achieves is to reach like 2 months per sec, atm that is not remotely possible lol.
But keep it up! Just keep balance/scaling in mind ;)
