The free version is NOT for commercial work! Go find a job, game making is not providing a stable income, only for some lucky guys that worked long and hard for it.

But, there are free/open source options like this:

P.S. Also, if you want develop serious for Android you need to test your games on many different devices (phones and tablets). If you can not afford a software for 100,- bucks, how you want buy this testing devices?

How you implement it? With physics? Or you wrote own collision routine? The walls are solids?

Have a look here (Audio Effects):

I think more HTML5 doesn't allow for now. But for short sounds you can

provide different versions without having too big files. Put three sounds in

one file, then chose the playing position with code. (with "Seek to")

Can somebody answer me, what are the best settings (visually) for a spriter project and how to prepare my assets correctly? I tried spriter in a test project, but the output ingame is not so smooth (i mean not the animation speed, the animation works very smooth), but the images are jagged or blurred. Is it better to import my images very big in spriter and scale down in C2?

It's like writing a novel...some people just do it with every shit pen they find on there desk, others always wait & wait for the perfect novel writing software. And in the end they wrote nothing.

I prefer to make my sprites with pixels.

tictoctic: This sprites i made free for you, so they are free for everybody. Custom work costs money.

But you can alter the sprites easily with free software, like Gimp or Inkscape.

I made them with Inkscape. If you want i can send you the Inkscape vector file,

then you can change them how you need.

And I need a lot of money and a cold beer...ok, the beer would be enough for now.

Stop spamming all the board. One thread is enough!

There are a lot of good tutorials on how to make sprites

in the net. Study them.

You can make sprites with the free software Inkscape or Gimp.

You need an international credit card. I have the same problem here in Brasil because my card is only national. But you still have the alternative of buying from Steam. Here in Brasil you can pay Steam with a national bank transaction, too.

I made two squares for you fast. If you like them you are free to use them.

Anyway, if you want make your own game assets fast & easy i suggest you

use Inkscape.

Could you please write more clear what you really want, because this doesn't make sense for me.

Anyway, you can not use a tiled background as a sprite, if this is what you are asking.

You need to make a new sprite and give it the image you desire.
