I did two things last night. No, three:
- I went to bed.
- Before that, I tried Moon Cresta with the single-shot ship. God I hate this game. Even the first aliens, with their unpredictable movement patterns, get on my nerves. Clearly, I may not be the best player to succeed in clocking the game without the help of power ups, but I'll keep trying. Stu: you may have a point here.

- I tried Gradius too. Without any power-up but a single speed-up. And I have learnt something: difficulty not only increases the more powerful your ship gets, it ALSO increases *when you don't die*. Even with zero power-up. Case in point: end of second level, no life lost. The boss shoots quicker lasers than at the end of the first stage. I die. Battle restarts: the boss now shoots incredibly slow lasers.
It appears the ranking system in Gradius is far more complex than I thought.
Oh, and unlike Stu, I did not really *cruise* to level 4: I found enemies to be quite aggressive, rapidly filling the screen with all kinds of projectiles as I made my way through them with a pathetically weak Vic Viper. I guess I need some serious training here. I died in the middle of stage 4. I'll try some more later.
