Interesting story for such a small game. This could easily be like a prelude for a longer game in the future, everything was set up quite nicely. I did find it kind of strange how the map scrolled horizontally and not vertically, I have not seen that trick used and it added a unique mystery to the game. Also the enemy sprite, even though it was only one looked really awesome!
I hope you don't think I am being mean but even though this is good I did enjoy your other game better so I kind of hope that one will get some nice ratings and that others like it too.
