For those of you using ivod's guide: In order for a much easier 5-3(B) win, you need to sell 3 cannons and replace them with Shockwaves. This enables you to kill the mini boss before your screen is filled with so many bullets you don't know what to do. Just a friendly pro tip-if anyone finds an easier way to win, let it be posted.
Ok, 14th playthrough:
Get 2 armor upgrades to start
Almost get killed by a goblin, use potion
Refill lifespan
Get Sword Upgrade
Pass A Gold Voucher store...(what do those do?)
Make my way to a divine edge store, spring for the 200 gold price
Encounter a Dragon the very next event
1-Shot that mofo
Got an armor upgrade immediatly after
