Hmm, ok, I'm going to take into account what you wrote in 'Author Comments' and tell you what I think:
It's a bit simplistic, unpolished and bland. It's a good attempt, but not anything special or worthwhile to me as a user/ reviewer. The game/ your project does not have a page which explains what the purpose of the game is. I don't think there was any objective as far as I can see.
The use of colours in the game are quite good, however, the main character took me a while to locate. I didn't even notice her until I continuously moved here from left to right!
Now this is not to damper you as a developer. If this is your first attempt (or an attempt which just took a few hours), I reckon this could be at least a half decent project.
You need to take time (longer than what you have spent already) to make it average, let alone great!
As a reviewer having seen many games/ movies, I can suggest a few things:
1) You're main character HAS to be visible. Be it that she is coloured into the game (i.e., not just a silhouette of the person, which is very similar to the other surrounding scenery, namely PINK AND BLACK)
2) More imaginative background, or a less crude/ unpolished background.
3) Music
4)Action music, ie, hearing the character move from left to right, teleportation sounds, etc.
5) Usage of the full screen- I can see 2 white lines on either side of the game.
6) An objective/ goal
7) A story plot, i.e., WHY is she there, is that part of the game? Did she wake up into a living dream/ nightmare?
8) More things to do, i.e., jump/ shoot (optional),
Ideally, it doesn't have to be an action thriller/ racer etc....so long as you as a developer can interact with me the reviewer, via your game. This is the fundamental of any game. See how other developers do their projects just to get an idea.
I think you have a good idea here, but you need to add more ingredients to the pot before it can be called a game. Otherwise its like a turkey roast...without the turkey, or the seasoning, or the vegetables...you get the idea.
Sometimes, projects take more than a few hours to be great and I reckon you can definitely make this much much better if you spent a bit longer on it, i.e., longer than a few hours!
Hope this helps, and look forward to seeing more creations!
