Google Drive works exactly like mediafire, the only difference is that it shows you the contents of the zip. Click the file tab and download. I'll see if I can get to BF tomorrow on my home net since this net isn't capable of uploading there(it fails because of it being so slow).
Also, it seems like you uploaded the files by themselves. It's not much, but it would be easier for the player to have everything ready in its own folder.
General complaint is about cheapshots:
- Shaky screen with a large burst of tiny bullets is crazy to go against, I don't really know what to say. Especially since the pattern looks kind of random.
- The green UFO warping spellcard is a cheapshot the first time. I don't have much against it, since it only happens the first playthrough, so it's okay.
Another thing to mention, (this may or may not be true since I'm playing with pre17 for some reason ^^") your delay effect seems to have the wrong coordinates or something, since it looks like "graphical edges" appears ingame with the bullet delay.
This is only some things which bugged me. Overall the script is quite good, with some interesting patterns, fun nonspells and a great usage of effects.
