Hard to make progress
Too Complicated
Only game I’ve played that punishes you for playing
The "levels" (at least on Mars) are 3 bases in different locations with only slightly different challenges. The actual challenge is to your patience since research from one base (on the same planet) doesn’t carry over to the next base. This means you have to research things like oxygen tanks for every base. Why not give us new problems to solve, or add research areas to improve on existing research? Instead, the challenge is figuring out what research/facilities were a waste of time and resources at the last base and building the next base without.
