Pro Tips

Don't forget to create workers in the beginning of the game but leave a reminder of 100 minerals to build your firsts turret

Be wise on how you spend your minerals! Creating a lot of workers early will leave you exposed to alien attacks.

Use the turrets also shields to protect the planet. They can take hits if necessary!

Pause the game when you feel overwhelmed and prepare your next move

Have Fun!

Sorry for the late reply Joshua. Thanks a lot for your feedback! We'll make sure that for the next time we add some way to tell the player how long he has survived as well as some sort of feedback to know when you select a turret spot. It was kinda difficult to balance the game properly and we run out of time, we will try to fix that as well!

Thank you for playing our game and I'll see you around!
