Oh, now this is some old school point-and-click adventure of the funnest kind. Granted, I was never the sharpest knife in the drawer with these things (as the video no doubt proves), but I instantly had a lot of fun with it. The graphics are gorgeous, all characters immediately likable, and keeping the game void of dialogue really actually does a lot to make you feel like the caveperson having to figure everything out from scratch and communicate nonverbally.
It's a delightful demo that quickly establishes the world and the style of problem solving you'll be doing ,and I can't wait to see more of it. Best of luck on this one - I wanna play the rest badly.
