I come from playing Rocket League and both games have a comparable learning curve. “Easy to learn, hard to master,” etc. However, where Rocket League is different is that in the tutorials (since it has a basic and advanced one) it takes you through the basic mechanics step-by-step in a way where it is easy to tell whether you understand the mechanic well or not. The game Supraball also has tutorials that function in this same manner. I think the fact that this game is free, and the game of football/soccer is fairly universal will get many people to try it out but even I almost just gave up before I looked up more information online. Unfortunately you can’t trust every player to do that.
Best of luck to the developers and thanks for making a fun little game, I really wanna see this game become at least a little more popular!
