I am glad you liked it SleepyGary, yours seem pretty interesting too from what I can see in the screenshot ... and by the way, local co-op I think its just awesome! I miss having more co-op games around. Some time ago we developed some templates for local co-op but ended up not investing much in them to have a full game.
About being a demo, I had a story in mind but in the end I found that stop motion animation requires a lot of time and so we decided to make it just a demo lolol. I kinda liked the result and intend to invest more time on it to make a full game and see if there is still time to release it in Steam's Greenlight, while it still exists.
By the way, we have just updated it, changing the controls so that every click while on conversation will trigger continue conversation, that way you actually know that the text comes from the thing you clicked before lolol. Also inserted more little clues so that you know what you should do to get to the 'end'.
What about you? Do you plan on working further in your game?
