It looks very nice, but it seems a little excessive to have the medallions, spiritual stones, and the seasons together. That would be a really long zelda game.
Will there be a window for playing songs on the menu in case you forget them?
Of course, what we have added to the Project Zelda Engine is not really extensive. In Project Zelda Engine, all the Medallions (eight so far) and the Spiritual Stones (three) are 11 in total, while in the Nintendo's official game "The Legend of Zelda: Oracle of Seasons", the Dungeons are 10 (!) in total, plus some small dungeons that are not counted as dungeons, plus a complete 4-season system, despite LoZ:Oracle of Seasons being developed for the (poor) Game Boy Color!!!
The Project Zelda Engine for RPG Maker XP (an Enterbrain's platform which has been released at 2005) features/supports just one (1) more Dungeon than the Oracle of Season for Nintendo's Game Boy Color which has been released 13 years ago, at 1998, if this is a such comparison of the term "extensive" when our goal is to give an standard amount of dungeons on a modern 2D platform, for the gamers to enjoy and play for hours.
So why not doing the same (or better) in Project Zelda Engine, which is a better, and more modern platform than the Game Boy?
People may still think that the PZE is way too big, but, yet, it has been requested by the community for the creation of zelda games by the fans.
About the songs: Yes, the songs of course will be displayed in case you may forget the notes!
They will be shown at that black window you see on the upper right corner of the Quest Status Screen.
By the way, here are all the 10 dungeons of LoZ: Oracle of Seasons in case you are interested for their amount:
