Cool idea, but the game feels severally underdeveloped (and I don't mean the crashes, those are annoying - but not unexpected in jam games).
For example, the game does not explain that I need to click on the dog in order to move it, so on level 2 all my sheep walk into the dog and spread all over, this feels very unforgiving in an unintended way. There is an option to buy a fence on level 3, but I can't buy it, and I don't understand why.
Even if you did not have time to add an in-game tutorial, you could have at least included instructions in the game description.
But regardless of my user experience rant, the little details like the parallax effect in the main menu, extremely low poly assets or the nice background music (as well as the dog moving at super sonic speeds which is hilarious :D ) are nice touches and create an enjoyable experience.
