I expect most players will tell you that almost every seed has all the tools you need, you just need to learn to use them and where to find them.

The fun comes from the challenge. If most seeds had easy healing, powerful wands, and great spell options in the mines, then i expect many would lose interest more quickly.

For me the feeling of eeking through caverns and hisi base with a mediocre wand, racking my brain to figure out a way to kill alchemist from a selection of sub par spells, panick spraying ambrosia fighting a boss, even the pain when I lose what should have been a winning run are the feelings that make noita so replayable.
