Sloclap's game offered a fresh look at the football genre, closer to a real 5-on-5 game than EA FC, but users are gradually leaving. Problems with network code and desynchronization quickly repel players.
The author of an article on TheGamer portal noted:
The peculiar nature of the game engine - the way players interact with the ball and each other - has led to the emergence of certain "techniques" that are almost impossible to counter. The execution of some moves was so strange that it felt like you were suffering from a bug, rather than demonstrating real skill.
The rating system in Rematch also does not take into account the skill level - players of all ranks end up in the same lobbies, which turns leveling up in ranked games into a race against time, rather than a race for skill.
Indie studio Sloclap faces limited resources: new features are added slowly, bugs are not fixed immediately. These factors are gradually destroying the community, and a revival of the game's popularity is unlikely, despite the strong foundation of the project.
