So here it is, an engine, with everything you'd ever want. Quests, guilds, weather, you name it. Its there.

Autotiles are a special arrangement of tiles in order to make mapping faster, simpler and much more pleasing to your players.

Doors make eventing simpler by allowing you to customize warps to different maps and locations.

Dynamic Worlds

Don't you just get sick of all those boring dull environments? No more! AC has an animated NPC and Tiles system to make your world come alive.

Ah you weren't expecting these were ya! Every engine needs quests, the quest system includes all sorts of different quest types, parts and events. Credits for the base quest system go to Alatar over on Eclipse.

Conversation System
You know all those new games with conversation system? Yeah they stole it off us. Just kidding. Basically this system offers you unlimited and dynamic conversations with NPCs along with events such as opening a shop or bank, warping and giving items.

I did mention that with the final release of the old Crawle engine we would be doing something special. Those special things have been pretty much finalised (much like the Crawle update) and you should be seeing them relatively soon, hopefully this weekend.

We're hoping to update:
- Crawle
- Deus Ex: Drums of the Revolution
- And various other Sleepy games.
- The website.

Hopefully Siloman should go up for charity sale this weekend too, if it doesn't I'll put it up myself.
