Any way to check weapon progress?

Like I never kept track of how far I've gotten with each weapons and I need a few diamonds, but I can't tell which ones I used have gotten past the lava area.

The archive may help with that, but its kind of hard to navigate. You have acces to every of your runs and where you got killed. You do need to unlock it first tho (in a certain musician quest line :)

Not really until you beat the games last boss at least once. Then you can see the unlock you got on each heat ladder level. 0 heat being the default reward level.
