It doesnt take long to get the general feel of Impulsion. The first-person platformer has you running and leaping all over the place with two unique guns very quickly. While the game is clearly inspired by Portal, it is a very different experience. It lacks the deep lore and story telling found in Portal, but has much quicker pace that keeps you running completing level after level.
