The new rule is the timer starts when the player clicks the 'Click to Land' button on the planet information page.
Starting the timer the frame the player actually moves Lenny leads to timing manipulation that I feel would make the category worse, such as avoiding the Martian on Mars by waiting to move until the Martian can be avoided without stopping.
The timer still stops the frame Lenny's spaceship starts to open.
As a general tip, stopping your timer just after the ship opens makes verifying runs easier than trying to stop the timer frame perfectly and accidentally stopping it early.
I've removed my Mars run and will be making another attempt in the future using the new rule.
I realize I'm the only active player for this game right now, but figured I'd give an update anyway.
Runs can now be submitted for individual planets. Timer starts when player clicks the 'Click to Land' button on the planet information page, and stops the frame that Lenny's spaceship starts to open after disarming the bomb.
The game is now labeled correctly and has a cover picture, as well as the new background picture that jdl suggested.
I made some custom trophies using the trophy model that's found on Earth in the game. They are so small I might change them to gold, silver and bronze Lenny heads instead (like the icon I've added to the browser tab).
The blue text on this page was a bit hard to read against the grey, so I swapped the blue for Sluggee green and made the grey darker.
I'm open to any suggestions.
Cheers
