Not everyone is a pixel art artist. :) I like making games. Many of the free assets I use don't even require me to mention them, but I do it anyway. Some are free, but I still like to donate. The assets I use also cost money, and I have no problem paying for them. But if you want an asset that belongs only to you, it gets expensive. I've been making games for free for years, and recently also as boxed versions. I've been asked several times if I would make a collector's edition. But that also costs a lot, especially the time it takes to develop a game. I do all these things in my spare time, and I enjoy doing them. I use the Skorpion engine and freely available assets. Even if I could do all these things, the time factor would be very high. I'm always happy when someone likes the games.
