comboing is actually the only way to play.. the damage you do is your base damage multiplied by your combo. So comboing means doing like 20+ damage whereas not-comboing is doing like 5 damage. Enemies have defense which essentially negates the first X damage, so it's Heavily incentivized to combo. You might be right that it's too hard. I only had myself to test it out and I probably am very biased since by the time I finished the game I had been "practicing" hitting the sweet spot for quite a while lol.
