I seen the first game live on Google hangouts, so as far as game development concerned it is no scam and some people in this topic are jumping to wrong conclusions. The game looked smooth but it was only a short video shooting an opponent, walking up and down, jumping around etc. Could not really conclude anything on the gameplay yet.
Ofcourse, for the other questions and concerns I cannot asnwer, and everyone should do their own evaluation.
Thanks for the update! Do you know if they plan to keep updating the game like Angry Birds (new levels and features and what not) once they move onto the next game? Or will they just focus on the new game?
I think they will be updating the game with new levels and stuff. Once the mechanics is done the rest is just short term building for the additions. But i am assuming.
