They look wonderful! However, I'd advise you to not start from the idea "plays like Ginormo Sword" because that leads easily to ripping it off. Especially when you're going to use a similar graphical style, people could connect a similar game to it and blame you for ripping it off. Instead, you could start from the idea of 'similar graphical style' but try to derivate as much as you possibly can from the idea of the original game. Those assets would also make a very nice sidescroller or even a light strategy game. Of course the good thing about a Ginormo-like would be the simple code, but there are sure many other types of games that are easy to code. For example, you could take those assets to a simple DungeonMaster-like dungeon roamer!
tl; dr: The art looks great but look out with the idea!
