Raptor Evolution

It's really fun seeing the next evolution and how it changes the raptor. But I am stuck and can't get the 2nd egg. It says there is a key that you need but won't tell me or show me how to get it. Same thing with the missing valve, I tried looking around the whole map but can't find anything, so I'm stuck, and it's super frustrating. If anyone or the developers can help me out with this, it would be much appreciated because I can't find anything online about it.

I genuinely liked this game, the gameplay is fun and the graphics are nice. However, I don't think it's playable because of sheer amount of ads you get for no reason at all. Some games offer to watch ads for extra recourses or to cut down upgration time but this game gives you unsolicited ads every few minutes and it sucks out all the fun you could be having. Therefore unfortunately I will have to give this game 2 stars

I thought I was playing a game, in reality I was watching a constant commercial with some game-play every now & then!! This game would be a great game, BUT AS USUAL YOU HAVE FORCED ADS RIGHT I THE MIDDLE OF THE GAME!!! Of course, I can pay to "remove ads" but I'm sure there is a loop hole in there where we pay to remove "forced ads" but you'll put in other ads. Too bad!!
