Hey there! Sorry about taking it off the Dropbox. I had basically decided to re-do the engine since it was so messy and rigid, but I'm still undecided as to whether I'll do it in Classic or C2. Anyway, there are some things missing in it, though it's a lot cleaner and much more versatile than the previous iteration, as it can handle faction-on-faction fighting and allows for factional relations to change not only with the player, but with other NPC factions as well.
It plays more similarly to an adventure game now, too, though the goal is still to make it a point and click action RPG. Unfortunately it doesn't seem like I got back into making the inventory and equip systems just yet. Also, right now it bugs out if the MOBs see each other and enter their attack modes, so I guess I haven't finished their behavior yet (though it is fairly simple to do, really). If I can dig up the old one I can put that back up too, but for now this is what it's come to.
New Action RPG demo
I probably won't be working on this any time soon, as right now I'm working on a Construct 2 platformer that I decided to tackle due to being easier overall to work on. However, that doesn't mean I can't help you out. Was there anything from the old demo you were looking to replicate specifically? Any of the systems mentioned in that thread I'm pretty sure I can help you with, even if it is just to push you in the right direction.
