Thank you for playing and for the honest feedback! You're absolutely right that the controls were too much to take in upfront and the purple lines (blood gates) needed way better explanation. I've just pushed an update that adds a proper training mode which walks you through each mechanic one at a time: movement, speed, rotation, formations, shooting, gates, and the destroyer bomb. No more guessing what things do. Also good point about the empty areas, some zones could be scaled down to keep things more compact and intense. Appreciate you taking the time, your notes genuinely made the game better.
