Here is my current project - it has the subtitle 'sunnyland edition' because of the great graphic-pack I use. I have to adapt it a little bit to my needs but it fits great to a puzzlegame. This short video shows the simple gamplay (endless), many things are still missing but the sound (incl. CDDA) works.. also on real hardware.
The gameplay isn't complete yet, I still have some ideas that aren't added. After that i'll take care of the other game modes.
