My approach.... Stick it on greenlight and see/hope/pray?
Draw on the mighty vast resource of allegro.cc and it highly influential members.
Implement al_init_mind_control (*global)
Probably not much in reality, maybe stick up a couple of new blogs, "jambon" (a fine class of spam) a few appropriate forums (rather than splatter-gunning everywhere ergo spam).
Sell five copies, though this time to be honest I have an official target of 50 sales that I would like to make, after last time getting ~20 for my android allegro game.
Sink into a pit of obscurity, except for the occasional reference in allegro.cc threads when I mention about that game I once made.
Forget this game, and start work on the next one.
