Surprisingly great platformer, belly or no. It's one of those rare platformers that requires both platforming skill AND actual thinking, where you'll sit there and redo a level a few times, realize you're thinking about it the wrong way, redo it, fail the platforming part a few times, then nail it.

Either way, you play as an MLP pony that eats meat(?), maybe it's actually "haysticks" or something, knowing the show. Then again, MLP OCs rarely stick to the herbivore thing, so maybe this is actually cannibalism, or Equestria just opened their first-ever industrial chicken harvesting and butchering center, heh.

There's several sizes to fill up to, and the last two sizes can break through platforms, but the final size is immobile since she's too big so you just drop. All but the last size can jump, and each jump height varies based on your size. The game utilizes this pretty thoroughly.
A few later levels introduce dumbbells that make you lose a size tier, but there's only a few levels left by the end of the game. Surprisingly, these are handled really well too.
When you beat the game, you get a final reward screen of the MC just really big.

I'm kinda annoyed at how good this game's platforming mechanics are, it just makes me want more of it.
