I have seen some small spelling errors in Ch 4.
During Heatran's battle in the sentence "Groudon open her mouth wide and fires back with ehr own burst of molten rock," the open can be "opens" and the ehr to "her".
Next is during battle with Arceus with the sentence "Arceus's body glows brighter and her huce tits start to bounce as energy builds" the huce can be huge.
Next is after battling Arceus with the sentence "Arceus has a point, you did know up her daughters before meeting her," the know can be "knock" up her daughters that would make more sense.
And last one I found is when the MC visits Rayquaza in her dream when Cresslia says just after the picture of Rayquaza picture "This seems more life it would be your dream" the life would become "like" to make more sense.
Still an awesome game.
