no, i wasn't scared by the game itself but my current project has the same basic idea and the thought of others thinking that i'd copied this game scared me. however, my ideas for gameplay are significantly different so that's a big relief but as it stands, the principal ideas are the same which still scares me a bit!
i'm not really going to divulge my game concept at the moment but the game that the above link will take you to will provide you with a good idea of what could be expected. i will look for assistance at a later time when the design documentation begins to reach completion.
