Do not be upset by the various fight-related difficulties in early game; you can use the tokens to upgrade some of your attributes :
- Dexterity (Yoga class) gives you a wider perfect-space.
- Strength (Fitness class) gives you a bonus in stamina (to resist the various enemy attacks)
- Intelligence (Library) gives you a wider "generic-damage" bar, thus reducing the % of a failed attack or defense.
It could be hard to reach because you have to pay 100£ to obtain the Library Card or the Gym Pass, but you could sell the DIY toy for a good buck, then you use the upgrade token you obtain in the end of each level of the factory dungeon.
In the hope of these informations helping you (and others) to appreciate this game.
