Nice theme. This is pretty much just a 3D platformer with no special mechanic that fits with the Game Jam Theme.
The obstacles could use more balancing and since some are almost impossible to cross unless I'm very lucky. Respawning in the beginning was a bit of a pain once you realize where you need to go.
The overall look of it was good but the gameplay needed more refinement. I am not sure what is the deal with the killer sheep versus your sheep. It would be nice to have some sort of introduction.
The second puzzle was a bit of a dark solution which means you need to kill yourself for each button. It would be nice to at least live to solve the puzzle though.
The development of the game was seen through but it need more playtests and refinement to make the playthrough less painful.
