Main idea: the player has to do some timing based clicks that are not too hard but not too easy then it gets more intense.
Secondary idea: the level starts as an ordinary 4-6 star with easy and slow clicks and with new modern deco and maybe some ship gameplay that uppers the difficulty a little bit.
Some basic tradeoffs:
I would choose to spend a lot of time making my level look good and have good and enjoyable gameplay rather than it being boring and bad but i finish it fast
