Thank you for your kind words!
For the jump: we knew that this would maybe slow down the movement a little bit, but we wanted the player to feel like he is scaling the cube by himself, but thank you for the feedback.
We tried to make our entry as polished as we can while also adding a bunch of content. The personalities would have gone even further with possible dialogue if we had the time to do it. If we look further into the game in the future, we would probably add things like that to round up the player experience!
