Thanks for trying out the game!
Unfortunately, I did fail to put in a tutorial to explain that well. In the game's current state:
- Light blue damage is slash damage which only the swordsman is able to inflict.
- Purple damage is magic damage which the only the mage inflicts.
- Yellow damage is blunt damage which only the paladin, who is inaccessible due to a bug, inflicts.
If you inflict the same damage type consecutively on an enemy with armour, it will be blocked (does 1 damage). This way you need to mix up damage types on the same enemy to do full damage.
The more I write this explanation, the more I realize that a quick tutorial and/or better feedback would have been very beneficial.
Thank you once again for the kind words, and for reading that wall of text if you have. I tried to design the story and general atmosphere around the artist's characters and monsters art to achieve maximum synergy.
