The pop-up book adventure game Tengami looks phenomenal if the following trailer is anything to go by (and you'd hope it is). Once the transitions between pages show themselves along with the tabbed puzzles, you're hooked (as the art design and music is enough to entice as is). Have a look for yourself.
It was slated to be released this summer, but the developer's blog has stated that there's a lot of work still to be done. Let's hope we don't have to wait too long, because this looks fascinating.
