What is Reddit's opinion of Survival Online GO?

From 3.5 billion Reddit comments

Just like with other online software free deals (Xbox free games each month), if you have a moment, just install and cancel/uninstall to lock in your purchase on your account forever.

I have old devices on my device list for Google Play, so its easy enough to tell it to install to those devices to lock it in.
