Well done ! I was wondering about an RPG without an inventory system myself. My idea was to have minions about who carry things for you, and which maybe you could direct to do things for you as well ("hey you with the key, open that door"). But that was not something I felt comfortable doing in two days. :-)
I like that you can throw things, rather than just drop them. But maybe throwing has extra uses ? Like throwing a key at a locked door unlocks it ?
