—, Thanks a lot for the feedback!
How long did it take to load? 10-20 seconds or longer?
The size of the game is about 30Mb, and it's hosted in Australia (which is famous for its crappy internet speeds), so maybe that's why it's loading so slow. It should definitely be faster once installed on the phone.
Planets rotation is intentionally made to be one step at a time, because each step uses 1 energy and the energy is the most important resource in the game. If I allow to rotate planets freely, without stopping after each step, the energy will be drained really quickly.
When you see 3 yellow planets scattered far away from each other and you start bringing them closer, you will quickly realize that this is not the best tactics, as you are losing too much energy. So you have to be creative and plan your moves.
The game is going to be free with IAPs and ads. But there is no "paywall", it can be played without spending money. When testing I completed all 200 levels several times without making a single purchase.
