i got the fedora! it has a really cool effect! this is a very good game. also maybe you could increase chest spawn rates only in magma zone? i haven't found 1 since my last 20 runs.
As for magma zone chest spawns, only titanium and diamond chests appear there, so they're intended to be quite rare, especially after you've found all the one-time blueprint chests in that zone.
yea the problem is that i don't have 2 blue prints. the diamond pickaxe blueprint and the magma boots blueprint (i assume they are called that.) and i haven't been able to find them.
