Easy to create games

Script file to make up game is very simple and easy to understand. For example, to show a background picture, just write

@bg sample.png 1.0

Then you can change background picture to sample.png with a 1.0 second fade-in time. “bg” is abbreviation of “background”.

Suika2 is optimized for CPU execution. It achieves fast and stable drawing without depending on GPU. If your CPU supports an extension like SSE or AVX, Suika2 uses it for faster drawing.

While Suika2 has good features, it is not so popular at the moment. I therefore offer you direct support by the author as a promotion.
