The deafblindmute's answer is good, you could also try XNA which is suitable for side scrollers, but actually exists in 3D. Their is no one program for designing games, usually it is at least 1 programming language (therefore an IDE or compiler) and one or more art design programs (a 2D paint program, and / or a 3D asset design program, possibly a music / sound fx editing program too).

interest programming is writing the code (boring) that the cpu will later translate into pictures, obsticles, circulate, shape....and so on and so on and so on. As interest layout is easily designing the platforms, characters and different nice tuning. think of of it this form, examine the full interest making technique to modeling something out of clay. Programming is like making the clay and putting a huge clump on a table. layout could be like nice tuning each and every thing, layer by making use of layer till the whole product looks precise. regardless of the undeniable fact that programming is easily the place the funds is at, layout is easily the place each and every of the relaxing is. to boot programming takes hours and hours of fairly boring classes, yet once you like development something out of no longer something, this may be a good profession for you. regardless of the undeniable fact that if your greater artwork based, identity bypass with layout. purely a splash opinion, lol

I've been programming for 6 years now, and I'm 18. I'd say look for a starter programming language. look for blitzbasic or darkbasic.

you won't be able to just 'whip up' a game in a matter of days (though i have... but thats not the point)... you'll have to learn a lot first.

designing game program is easy , only u have to be good in the software programes like html , jave and most importantly c language. To include some design to yur program it is better for u to use the language html for multiple option purposes
