If you re-submit that same data information, it will be approved.
Personally (which doesn't matter for the database), Lil Gator Game looks to primarily be an open-world adventure game complemented by minor platforming and action segments. Genres are incredibly subjective which complicates how data should be submitted considering the database is focused on objective information, and it's the only field like this. When browsing search engine results, I saw one source define this game as a RPG. Also, let it be known that when I personally respond to Genre field edit submissions, I do not rely upon GameFAQs and or platform-specific storefronts like Nintendo, both of which I have previously seen wrong genre information attributed to games.
