FTL

https://subsetgames.com/ftl.html

Flee through space, repairing and upgrading your ship as you go. You’ll encounter pirates, aliens and entities who want to kill you, so be prepared to use everyone and everything you have in battle.

Genre: Real-time strategy.
Platforms: PC, iPad.
Difficulty: This has three difficulty settings. It can get really hard and, given your progress is reset when you die, difficult to actually finish.
Age-related suggestions: Probably better for teens+ given the complexity of game elements that need to be managed simultaneously.

Consider consulting detailed reviews before purchase.
