A few months ago (ok it was 10 months ago) there was a question on /r/Android about creating a game and I came up with an idea. I will post the link followed by my game idea

http://www.reddit.com/r/Android/comments/1xmx04/reddit_submit_your_android_game_idea_and_i_will/

"your character starts at the bottom left of a horizontally held tablet or phone and needs to make it to the door at the top right of the screen. the character can move left, right, and jump approx 1/5th the height of the landscape held device. the screen is a box which the character can't exit (besides the door), and the only thing else in the box are two platforms in the middle of the screen and two cubes that start at random points and bounce around the screen similar to a dvd logo on your tv. your goal is to jump onto these cubes and jump off when you get to the door, using the platforms to help if you need them. but watch out, the cubes can crush you! the cubes collide with each other but not with the platforms. when you progress to the next level you have the choice of: making the platforms smaller (which are objects that only help as they cant crush you in anyway even if a cube is passing by), adding another cube (more chances to get to the door, but more chances to get crushed), or making the cubes move faster (less reaction time)."

So since I made that post months ago I totally forgot about it until yesterday when I got a message from a developer asking some questions about possibility making it into a reality. I made a quick .gif showing how I thought it would look/work. that link is below.

Anyways, as you can see it looks TERRIBLE and I would be interested to see how someone interested in UI design could make it look more legit.

I understand if my particular game is not of interest to you, but there are TONS of app ideas on that /r/android thread I posted at the top of this post and I suggest you look through those to find a good idea. If you see something you find interesting just message the user; I am sure they will be just as open to further development as I was.

Good luck!
