I think that million point score was some sort of glitch. I haven't been able to come close to replicating it.
The game loops, but between the 100+ degree weather and, well, playing Gradius II, I decided to quit while I was ahead. Also, the first time I no deathed a game first time beating it.
Anyhoo, another notch for the leaderboard.
Using Imgur as the board is slow as balls uploading.
