Spoiler:

There are perhaps five minigames. There's another chase scene, this time with Rat Creatures and it's slightly harder than the Locust one since the RC occasionally have bursts of speed.

There's another minigame where you need to slink away from two Rat Creatures while they are arguing. This can be frustrating and there were a few glitches here that should have been noted by the beta testers. Nothing serious. There are a couple of times when you need to play hide and seek, once with Fone and once with Phoney. I can't think of anything else really.

So no, the chase scenes aren't the only minigames. There are some pretty neat ideas in Bone, but it really lacks some puzzles. In fact, as Phoney, you’ll use a tactic on Ted's brother twice. At different points in the game, that is. This really smacks a lack of imagination on the part of Telltale, considering the short length of Bone: Out Of Boneville, and even if it was in the comic -- which I cannot remember -- it's disappointing Telltale did not take it upon themselves to add their own "bits".

I haven't read the comic for a while but it adheres very closely to it as far as I can remember and pretty much everything from the comic is in here. Yes, I'd hazard that everything from the comic is in the game. I can find out by emailing Telltale too.

Basically, you reach Grandma Ben's farm, do some chores as Phoney and Fone. Then, a cutscene is signalled and you wake up in the night to find Rat Creatures have surrounded the farm. You, as Fone, must run away from the Rat Creatures. Once you've done so successfully a cutscene is triggered as Fone, Phoney and Smiley re-unite at the fair, with Grandma Ben and Thor watching. The game truly ends as a mysterious voice concedes that Phoney has been saved by his cousins this time, but that it won't happen again. Then the credits are brought up. You don't know who the mysterious voice is or why he/she wants Phoney.
