The concept of this game is actually quite interesting. Unfortunately, I did not get very far to see the mechanics really explored in depth. There seems to be an issue with the game that dying on certain spikes (see the spikes in the first picture) will get the player stuck inside a wall (see the second picture)!
Also, one other weird thing was that the knight seemed to always move backwards? Is this actually the case or is the problem just in my head? For example in the first picture the knight looks like to watch towards right. At least that is the direction that the eye hole of the helmet seems to be pointing at. But I was actually walking left towards the spikes before taking the picture.
