So, I updated 2D Physics; better interface, Editor, you can save up to 100 files and more music (for the editor too).

You can edit the files manually, if you want. Comments were added, so you know, what you're changing ^^

I'm looking forward to fix uploading on the server; I look for a not too expensive tool with http (maybe fdp) for uploading and downloading data with 3dgs.
If anyone know one for A7 (cheaper than Anet), please post
