I like everything is this game, even though the dev turned out to be... something not good, because he/she took one game down from the portal. However this is a review for this particular game and it deserves praise as it has everything well done, from the pixelated graphics to the soothing music which calms people down in order to avoid material damage, to the squealing that provides accurate feeling of being (in control of) a pig.
As for the difficulty curve, it is steep, but learning how to is not complicated. For those trying the speed run medal... LEARN TO TAP. And use Z to fly. Once you do both the game will become much easier
