Woah, hugone! Just noticed your example with perspective jumper and was in... awe, mucho!!!!!!!!! 8-) Close to what I was intended, thanks.
Tweens and Bullet: Bullet is dynamics, would not vote for it anyway, as it is suitable for different gameplay concept. Why would you avoid LiteTween? I thought that LT would give more intuitive control over trajectory adjustments, like for variable jump heights, quicker to set up.
I like your Case (move) branching, makes entire code more structured. Is this still hardware independent, since you use dt increments?
Your example made me completely reconsider my approaches to the code, as I naively thought that everything must reside under everyTick. I will post an update with what I ended up. Gracias!
