Dull as dishwater. MMO type missions that require nothing but standing next to things. Constant ads. There really isn't much of a game here. 15 minutes in and I was bored stiff. Get meat from humans which is progressively slower as they level up. So you upgrade to make it faster, resulting in no change at all. Don't waste your time, this is not engaging even by the standards of modern mobile 'games' which are really just time sinks that ultimately go nowhere.

I love this game. lots to do before level 15. However, once you hit level 15, that's basically it. You can keep levelling up skills, it dose take some time to keep going with levelling them up. I would really love for more levels to open up. Also, to explore the other world that is coming soon. is there any time frame as to when this will be happening, please? I've given the game 4 out of 5 only for not having the extra levels. Once more levels come open I will change it to a 5 out of 5

The first part of the game is fun and interesting, watching your alien develop. However, when you get to the ice level, everything stops, you're back at square one, there's nothing to do and farming is slow, so slow it's super dull. There's nothing to do, no missions and after all your hard work, you're alien is worse than at the beginning of level one. Why? Slow and boring...
