Hi :D Thanks for playing our game.
Yeah, it was not intended at first to have a "perfect 3 sheep across" and more of a "Get as many across as you can" thus the player can only restart through pause menu. But thanks to bug and time, we have to scale it down and indirectly forgot the game should be able to instant restart even if a sheep die.
But on the other hand, not forcing the game to instantly restart allow the player to test out the level. The first round, they don't have to get all sheep across. They can try to learn the map and the tactics to get at least 1 sheep across.
In a way, this feature of instant restart would be nice to have as an optional toggle in the menu :D
