'Before his Eyes'. The link is in my signature, the active projects list and is on the first page of 'projects' There's a trailer / demo. the demo is a little outdated (Final-Knight made some maps for the emptier areas after chapter 1, but i've not included them in the demo yet)
(as a note, the demo has no official end. but after the 2nd boss things start to get very ''i've not built stuff for that yet'' but you'll know (i'm sayin' this just so you don't think ''hmm...chapter 1 is crazily empty...'') and the maps in chapter 1 only really include what you need for story, they haven't been prettified yet)
Feedback would be much appreciated, thanks in advance if you do try it.
