because on steam the game is paid if it is free here what is the difference the same on the playstore it is free

First off, I love your game. Wow. Blown away. I just came from mobile and a lot of things are different so far.

I can't pause and pre-set builds as my position freezes along with the pause unlike mobile. In mobile, I can actually move my screen and build in different areas (I may be remembering this incorrectly.

Also, I sent up my typical vent ammo ramps with junctions and they don't seem to work on PC while I know for a fact that they work on mobile. Here is a pic:

I hope I am misunderstanding something as I am very happy with my mobile experience.

Great Game! This is because of these big features, easy multiplayer, great content, and fun game graphics. First easy multiplayer it is very easy to connect, just host and appears on the local network even in bad internet. The game graphics are an interesting blend of kind of pixel like  and rudimentary shapes and gives a simplistic look! The content is also amazing and everything seems very balanced. However, I have one compliant there is a bug with the wraith and i think all flying drones. They stay still if not called upon. But, overall great game!! :D
