I honestly had a super hard time with the first orc, so I decided to just grind slimes and octopus monsters for levels. I got lucky and one of them dropped a chest with dash shoes. Once you unlock dash shoes, the game becomes easy mode honestly. You can dash at monsters from far enough away, and attack them in the middle of your dash. The momentum of your dash will still carry you past enemies after your attack hits them and they can't hit you back cuz they are too slow. Rinse and repeat. It works on every monster or boss provided you have enough space, except the lickers. Bosses have really big health bars so it takes a while, but you are completely safe doing this. With Medusa, you just have to be careful not to accidentally run into any fireballs.
It only works with dash shoes however.
I wasn't sure what slime and the lewd crest even do though except maybe raise the lewd level?
I'm not even sure where I see the lewd level though.
I do appreciate the two different gallery modes available. (gallery and prison mode)
