Its title sounds cool bit like mystery but the game's descr. rather more about the keys than what could be about the game, maybe quite more spoilers or hints before clicking the run(game)-button would be awesome in being added there?
The visuals and graphics are cool, especially the vision from above, realistic walls (just my device quite lagging if games being directly played, downloads would be an issue of free space, anyway a youtube-tutorial like: possible right/wrong paths, possible encounters, etc. could be nice, which also being less laggy when viewing them).
I could add info if viewing streamed let's plays with cam too, details about sound, features, possible typos, etc.
