About this game

Travelling and exploring in the vast universe, your spaceship approaches a new galaxy... All planets are destroyed here and aliens are all homeless and helpless. What happened?! You really want to do something for the aliens. You have landed and made short stays on many planets. Now you decide to stay here to build planets for the aliens!

This is a simulation and strategy game with the theme of space construction. Your spaceship arrives in a galaxy, but all planets here are destroyed because of an explosion. Your main mission is to re-construct home for the aliens on the ruins/cores. To build planets, you need to collect matters, unlock environments and seek microbiology. The more resources you collect and level up, the more planets will be constructed. There is no doubt that the aliens will help you to build the planets together. You can also accelerate the speed of construction with the help of space station. Do not forget to explore with a spaceship to get more fuels for the space station!

Game Features:
* Idle and easy gameplay. Resources can be collected when you are offline.
* A way to know the essential resources for life.
* Unlock numerous alien cards and accelerate construction speed.
* A space station to speed up the process of building.
* A mining feature to get more resources and upgrade your spaceship.

Game is really fun! Unfortunately my app closed during tutorial of space and how to transport goods (right before using gems to speed up). Now when I open game it only shows the plant and won't let me do anything. Hoping this can be fixed. Waited some time and was able to log back in and play again.

It eventually becomes pay-to-play because the goals get more and more demanding, like wanting you to spend 14,000 points for a level. It can take upwards of a week to even think about earning that many points passively with the ads, treasure chests, and level upgrades etc. :(

When I watch an ad and then don't get the reward, I feel cheated of my time. You need to ensure you fix the bugs to prevent this. I've uninstalled and given low rating because of this problem.
