Lot's of cool stuff in here. I like how you started it with a tutorial. I'd recommend: Moving the ingame text (e.g. "Open Chest") into the UI canvas. It's easy to get calculate the ui position from the world position. The night-time is ridiculously dark where it's unplayable. A roman camp would have torches and stuff lighting it up. The game could do with being brighter. Quite a few random bugs and little problems encountered which just need polishing up. Clearly a lot of potential here. 

Ran into a bug where the pause menu kept popping up after leaving the inventory and wouldnt go away. Other than that it was a good start!

UNCHANGED SINCE LAST DEMO DAY'S FINAL BUILD!
So if you played that version already, don't bother.
