I'd recommend playing Unnamed Space Idle instead. It's a free incremental game with optional in-app purchases that gets more complex over time as additional ship systems are unlocked.

Edit 1: Added link and basic description.

Edit 2: Not sure why I got a downvote; just trying to suggest a game I think most people will prefer (96% positive versus 48%) without the need to spend a dime.

Already finished it seems!
