A few more things I’ve noticed:
While “Adventure” is one of the most poorly defined genres in gaming history, Lost looks more like a “Platformer” than an “Adventure” to me (me, who hasn’t played it). You don’t have to change your description - but if I’m right about that, you should look into changing that tag.
Also, like I said before: Your game looks good! Hence you should consider adding more screenshots. I don’t know how many stages it has, so saying “One per stage, please.” seems a bit risky, but 4 to 5 screenshot of different sections of the game should give the reader a nice spread to tell whether they would enjoy this game or not.
And if you don’t list anything under “Platforms” (Windows/Linux/MacOS/stuff…) it won’t show up in the search if users filter for their specific platform of choice.
Speaking of the search: If you can come up with a (very) short summary for the field “Short description or tagline”, that text will be visible in the search as well. I can’t promise that it will help, but it seems unlikely that it would hurt.
