Yeah, the default typing speed is approximately 40 words per minute, which is apparently the average typing speed, so it's not unexpected that some players need to turn it down.
The gameplay is definitely very typing heavy, though honestly, I'm fine with it this way. Most of the visual novel genre can be summed up to "you click buttons and read", so I think it's almost expected from one that most of the entertainment comes from experiencing the story. I do understand how this can be jarring to someone expecting a more gameplay heavy experience though.
Thanks for playing!
