Hm, just wondering about some things:
I made it until the first boss through basically avoiding most enemies.
Defeating him would require me a big amount of heal items or better equipment.
The last one is not availlable and healing stuff costs a lot of money.
And the only money source I see is selling flowers. (Or destroying stuff which takes even longer)
I can rise the friend level of an npc by talking to him over and over again.
And I can actually kill them with my weapons.
Doesn't matter either way.
So now I'm confused if there is any easier way to "get better" except grinding flowers to buy heal items (which takes an insane amount of time)?
Since as far as I can see, killing the boss is the only way to unlock new areas and stuff.
I'd say fighting monsters to grind levels is the primary way to get stronger. And you can craft potions! Fill empty phials at water sources and combine with some red mushrooms and a blue flower at any crafting pot. There are a lot of recipes that you unlock by having the items in your inventory. You can also collect apples from trees, but they don't heal as much. Sorry for the late response, hopefully this is a good tip for others as well.
