Hi! thanks for the feedback, really helpful, we will take it into account! So a couple of things, referring to the purple/pink character is supposed to be an npc but since there isn't any lore yet it's understandable the confusion. As per the levels, we are aware that the difficulty spike varies a lot, you'll noticed that some levels are harder than the ones that follow them. This is because we have yet to decide in which order these go, for now, they are ordered as we designed them.
Still, really appreciate the feedback and stay tuned for following updates! :)
