Feature Changes:
The J35 no longer offers a ground attack option for better realism.
The J35 is no longer damaged by enemy targets when passing through them, reflecting its stealth capabilities.
A countdown timer (10 seconds) will appear at the start of a wave; the first enemy target will only spawn after the countdown ends.
A chapter selection interface has been added to the campaign mode, triggered by the "Chapter Selection" button in the upper left corner. (The demo version only includes one chapter.)
