Never seen anything like this!? It's a shooting and running game where numbers shoot numbers and merge them. Shoot the numbers in the stage to make them bigger, then collect and merge them. The more you merge the numbers, the bigger they become! The more you destroy the number walls that stand in your way at the end of the stage, the more money you'll earn. With that money, become even stronger! Now, how many times did I say 'numbers'? ※"Money" refers to the in-game currency --- Rated for ages 3+ by IGRS (Indonesian Games Rating System).
