There is an array object/plugin in C2, but it's hard to use for beginners.
And, although it IS a typo, tactical games are hot to make. Learn to use C2 on something simpler, like a platformer or a Zelda-ish type of game. Then, learn to use arrays, experiment with them on your Zelda/platformer game, then proceed to making a platformer game.
P.S. I would very like if non-English people would say what their native language is, never know who knows what language in the community :)
