I see potential
Instead of just commenting on the graphics or the music, I will try and offer my opinion of what you can do to improve flashes after this.
One thing I thought was good was the controls. My character moves smoothly and can't squeeze thru any walls. You seem to have the hit detection for both the walls and the traps down.
I also like the concept of repeating the same level over but with different traps. If you get more into this in a future game, and add elements that require more critical thinking, make it so you have to completely rethink how to go thru again.
The graphics have room for improvement. You can tell what drawing tools you used for what. If you can use a similar style of the graphics in your game as in the title, it will look much better.
Keep at it, sped a couple extra days on those flashes before submitting them. the end product will much more satisfying.
