Eh- it looked pretty good, the game has a very nice minimalist feel to it and the incredably high jump makes you feel agile. However, the random level design and confusing portals mechanic makes the levels difficult to navigate and don't compliment the high jump mechanic as you're generally stuck underground. The falling blocks stop the player in his tracks and stops the flow to the game, the places they are located often just kills you after you navigated a difficult section. Without any form of checkpoints and the fact that you lose a bit of what you are carrying it can get frustrating, I would rather they weren't in game.
The timer on the cow levels seemed to have no reason other then to stop you in your tracks. There's no reason to it, nothing to suggest a danger and the level is filled with falling blocks.
The look of the game and the animations are well made- the game play does need a bit of work though. I wish you the best of luck!
