Thank you for playing the game and for giving feedback!
Indeed, the balance is currently very bad, that will be fixed and I also plan on introducing incentives for decreasing the other stats too along with other methods of approaching fights.
The possibility to reduce your own stats was mostly a setup for content that didn't make the cut, for example, I had in mind an item that when held would increase the player's attack by 1 for each negative armor they have, sort of a berserker item I guess.
Glad that you had fun with the game even with the state that it's currently in XD
