Challenged as an artist, but not a gamer...
The main flow of the game is rather simple: the rapo-mayor asks you to get a specific page for the book of life, you enter a level, you kill pathetic enemies while rescuing rapo-villagers and hunting for 4 pieces of paper, you return to the town, you talk to the mayor, you color a new town item, and finally, you tap dark clouds away to reviel new parts of the village.
You can draw and color up to 3 playable characters, 17 rapo-village items: (the sun, trees, building, ect.), 6 equipment items that your character uses in the levels: (gun, sword, wings, flippers), and MANY in-game objects that helps you get through the levels (clouds, springs, ect.).
There are 15 normal levels, and 4 boss levels. I , sadly, had ample challenge on only 2 of those levels, (Windy Hills, Shadow Lair)
Thankfully there is a shop in town that lets you buy (with the money that you get in levels) patterns, stamps, music, minigames,and special abilities.
More later, I haven't the time...
