A couple of years later I released May and Yam 2. This time I avoided ripping stuff and drew all the stuff by myself. This game is no longer related to Pang! It's just a single-screen platformer where you need to collect items, while avoiding monsters, to progress. Some screenshots here,
Both games can be downloaded for free. You will need an Amiga computer or an emulator in order to play them:
As the person making the longplays found out, May and Yam 2 has a bug and the game ends abruptly before the last stage. I'm sure I made a version that worked, but unfortunately I can't find the disk with the working version. I could fix the code, but I think I'm missing some assets for the ending as well...
If you want to take a look at the original source code, it's open-sourced here,
