Been loving the game so far but progression is pretty slow. Definitely not meant to be played for a long time in a single session which is why I give it 4 stars instead of 5. I love that ads are an "option" but I wish the rewards were just a little more significant so I could play for longer without getting bored or waiting for my resources to build.

Honestly, this is my new favourite mobile game for killing time. It can keep me occupied for ages. Yes it's simple, but there's always something to do. I'm on level 14 and I still enjoy playing. Progress can be slow but it makes it more rewarding when you finally level up or get the resources to level up furnaces, for example. The weekly challenges always help keep it more interesting.

Looks like they raised the level cap finnaly, it is just sad you don't get any updates to your alien by leveling up, just access to new areas. Over 500 trillion to unlock the last units is ridiculous. Edit: Fixed how many humans you can eat at once. The Galaxy mini game, 2 levels the boss never showed up and had to exit with no reward. Waited 30 min both times.
