I leveled up to where the nova could keep me safe with a scroll active, then to where it was constantly on, then I had the wizard take a nap in his bed (in the library, top-right corner, about 5 minutes), cleared out the goblins that had built up "overnight", used the enhanced speed to phase through the world border and ascended to godhood at level 69. Quite fun for a 72 hour game, but could use an actual victory screen out-of-bounds and certainly would benefit from a bit of enemy variety, though the map complexity is on-point and the 'advanced' enemy AI by survivors standards (the goblins walk *around* walls? and even move on paths when we're not around? D:) makes up for it somewhat.
