So I wanted to make a 2D game but had no idea how. And instead of trying and jumping into 2D game making, I decided to make a 2D short animation. And If it was any good, then I can start working on a 2D game 
Here is the short animation : http://www.youtube.com/watch?v=7aw1CUMvBkc
What do you think of the animation and what is my chances succeeding in 2D.
Btw, that was made in paint and moviemakes xD
Hi Mattyy! For it being your first animation, it’s not terrible but I would strongly suggest finding or commissioning some 2d sprites if you plan to do a game.
Best of luck to you! 
Oh well, I am not really sure how does this whole sprite thing work. Basically I just drew frame by frame using paint. So, Sprites are like the frames ? So few sprites make a jump animation for example ?
Mattyy, to really understand the scope of animation of any kind- not just sprites- I strongly recommend reading The Animator’s Survival Kit by Richard Williams. It’s absolutely indisposable if you’re considering animation of any kind, but especially 2d.
A sprite is a separate image or part of an image. (the term has many uses depending on the context). Usually a sprite in 2d game animation refers to a single individual object on the screen. That may be a full character that has a series of images that being replaced/swapped on the that element to create animation, (like zelda/meatboy/swords and sworcery/etc). Or if a game uses puppet rigs or similar, the individual parts like the head, arms, torso would be sprites.
It is just a an element that contains image data that independent from the background and other elements.
A frame is just an abstract way of tracking states in order. Though related to time, and usually linear, the can also be controlled, progressed and skipped based outside of the linear progression of time.
Depending on what you are doing, and the way events are handled, and if you are mixing in procedural/time based animations as well, it can get complex very quickly.
The book recommend by Jackal is definitely a good place to start.
