Thanks for that; unfortunately the issue still persists. I believe `card.pdi` is supposed to be in the `launcher/` directory (it's currently in the root). Sorry for the trouble!
Superb Suika-like (if you don't mind me calling it that). The missile mechanic is a very welcome addition, allowing you to play longer, but you actually have to work for them so it doesn't exactly introduce a, well, easy mode. Oh, and did I mention the soundtrack is bangin'?
