I do personally think daily updates are a lot. However what you should really do is look at your pages and think about what the best update schedule for the flow of the story is. Maybe two updates of two or three pages a week? Or maybe not! Just be thoughtful about what you think will suit you.
I do think updating more than once a week potentially will mean faster growth, but you still have to make sure everything else is on point. I looked at the comic, and it's pretty cute. I think it's possible making comedy the main genre instead of action might help you market to the right group of people? Even though it's very action oriented, it seems like people looking for comedy that also like action are the ones that are going to be pleased. Unless the story builds into something more action oriented than a marble game. (I only read the first few pages, so apologies if this change is evident)
^Also want to note I spend more time in the romance and fantasy genres, so I'm very far from an expert in the expectations here. It's just a thought I had.
I'll follow that up with your story description:
The marbles game everyone is not familiar with.
This isn't very interesting! It's only amusing if you already know what the comic is, but assume this is the first thing someone looks at after they see your thumbnail. You should think about how you can attract people to your story, and beef this up considerably!!!
*Second what others have said. Regardless of your update schedule, two weeks is a very short amount of time. Webcomics are inherently a slow and long process in almost all cases. It's more an endurance run than a sprint imo.
