Will be interested to see how the stealth component works with the "fast paced" description from the concept statement.
Lots of great games listed in the influences for this game, and the concept art gives a good feeling of what the game will be like already. Idea seems feasible with a sensible pathway to success with some features identified as nice-to-haves (I agree with the chose to make classes only if there is time). Can't wait for this one!
