Today i have run into a Humble Bundle 4 for Android
Which contains a indi game called Eufloria, which i was not aware of before

The bundle is pay what you want for 5 games, for all your platforms, and also Steam keys for convenience
(this Mars cave exploring Game looks nice too) ...so i gave the package a try
Eufloria reminds me off a slow 4x space game were Strategy is actual needed and paying off.
with a unique design and some 'Zen like experience' watching the situation unfold
I am 5 missions in the tutorial campaign on the tablet atm.
Here's a link to their page where gameplay videos can be found
