Homebrew coder dan369 has released a demo of PSP Mario, a simple Mario game written in Lua using PGE. The gameplay feature is almost the same as the classic Mario games but with better graphics and some custom animation.
Since this is only a demo, only one level is available for you to play which is a re-make of the first stage in Super Mario Bros. for the NES. The dev expects certain in-game things to be changed and added in the next release. On top of the devs list are additional levels, a level-editor, enemies and more items. So for now enjoy the demo.
