Odd that there's no comments on this one since 7 people have rated it.
I thought it was fairly simple overall, the gameplay itself consisting of walking and pressing W and S when prompted. This made the fight against Goliath fairly straightforward, though also kinda unengaging since it effectively consisted of just waiting for Goliath to attack. I do like how the "tutorial" at the beginning mimics the actual combat though, kinda reminds me of how fighting the dummies in Jak and Daxter prepares you for the actual enemy attack patterns.
Overall not bad, but does feel kinda empty. Oh and FYI it is entirely possible to climb up onto the rocks and part way out of the map, I actually got myself stuck.
