Nice game! I was skeptical that a 3d game would actually work in a browser, but it did extremely well. Loved the plane fights. Reminded me of a game I played long ago, "Hunt for the Red Baron". The auto-flying here meant I had to focus only on lateral movement. Still, this was hard enough. Couldn't complete the game end-to-end, but did complete each part. Nice touch to add the option of going directly to the boss battle. Good job overall!
