I created this game as a kid, messing about with trading cards. At 28 I've now turned it into a computer game. 

You buy packs to get cards, you use your cards to beat the opponents. You have to win your way through Africa, then South America, then Asia, then an extra few secret bits oooooo.

The base game should be a couple hours of fun, then there are 'character games' where you run a playthrough as some weirdo to make it harder.

This is a relaxed animal card battler where you draw a random selection of cards from your deck, you then decide which card is going to battle for you in each of the categories and see if you win more categories than you lose, to progress. For example, your agility attack stat will go up against their agility defence stat. There are three continents to work through, with cards being better on their own continent, followed by the secret bosses. Will you get lucky and draw powerful cards early? Battles give money, money buys packs, packs give cards to hopefully make your deck stronger.

The progression is timed so that you can always rerun to try to beat your previous best time.
