Yeah, it's me again! 
Let's talk a little bit about the optimizations that the Android version received in 0.2.0:

I bought a very simple mobile to test the game.
The intention was to try to optimize the game to make it work on most mobiles.

Here are the specs of my mobile that was used for testing:

• Model: LG K10 (New)
• CPU: Quad-core 1.5 GHz Cortex-A53 + Quad-core 1.0 GHz Cortex-A53
• RAM: 2 GB
• Android: Version 7.0

As you can see, it's quite modest!

Taking this into account, I decided to reduce the quality of the animations to 720p, 30 FPS.
Mobile screens are small, so there's not much need for 1080p animations. (Renders are still in 1080p)
By reducing the framerate from 60 FPS to 30 FPS, I expected more fluidity during the animations and this was exactly the result!
The reduction to 30 FPS didn't spoil the animations though, presenting results almost as good as its 60 FPS version.

After this procedure, the test result was:

The game runs well on the device, the only problem is with heavier/longer animations, which causes a bit of lag, but you can play from beginning to end without any problems.

From this, we can come to a conclusion on what the minimum hardware specs would look like:

• CPU: Octa-core 1.5 GHz
• RAM: 3 GB

The Android version I believe is irrelevant, if it's not too old a version, I believe it will be ok.

I emphasize that the specs mentioned above are my deduction, but the game will probably work fine on mobiles with these mentioned specs or superior.

If you played on mobile and want to share your experience, feel free.
Feedback would be most welcome! ;)
