I love this so far. The style is fantastic and the expression on the pig's face is perfect.
The theme is hilarious and makes me think it could be applied to everything. Instead of coins, he's getting drops of water, to cool himself down...
One thing that came to mind — as the pig 'slides' i noticed he speeds up, which somehow felt contrary. I know you slide faster in soccer / etc... it just looked like he had hit the dirt, and should go slower.
If it's about getting through low spaces, maybe it's the animation that could be more 'slidey' (like megaman)?
Or if it's about speed, maybe a different animation (runs on all four legs, trips and falls (bacon roll), eats another chili, stabs himself in the ass with a fork, etc)
Anyway, enough unsolicited thoughts. Thanks for sharing, it looks fantastic!
