I thought 6.13 was faster! The problem is that Loren is really pushing Ren'Py tool to his limits, using screen language, python, and lots of animation, sounds, music at once. If the game was coded in C, would be much more smooth. But sadly I don't want to deal with C coding anymore, is a pain
One of my long term goals is to recreate such RPG system using a cross-platform tool like monkeycoder which should be pretty fast, but that won't happen very soon for sure (I still have to learn it myself properly).
