Re: [ARUMERO SOFT|RPG]Creature Hunter
Mechanically, getting through the game isn't difficult.
There is, however, one important bit:
The game doesn't give you anything for losing a level.
So don't keep trying over and over to beat a boss and failing, it'll get super repetitive and farm-y to keep grinding money for consumables.
Instead, if you can't beat a level, go back to the last few levels you can reliably beat for ingredients and money,
and after a few runs (depending on difficulty/playstyle) you should be able to afford upgrading your gear.
With proper gear, none of the levels are difficult, but there's a pretty steep progression in there.
