hi @GalMaron
Obviously no direct exposure then as @SergiyG has explained.
BUT indirectly it takes a few players to grab your free game, if they talk about it, or a content creator jumps on it by recommendation, it COULD indirectly get some exposure maybe?
Obviously you need something that has a good playability and captures an audience, like all good games.
Cant hurt? except a little financially but if your not selling much its possibly worth a try.
You need to get out and advertise. Showcase your game on the forums here and elsewhere.
