Journal #0.2 - Decision Making

I have decided to use the 2D Game Kit. Gamplay should consist of short tutorial zone, then some progressively harder levels, 2-4 of them, each whit its own special mechanic. E.g. one level takes place on the moon, so the gravity is lower, in another, you have to utilize Launchpads to their fullest in order to solve puzzles and so on.

Currently, I'm struggling with the idea of creating the whole design on paper and only later implement it, as I usually design my work on the go, but I'll try my best to pre-plan everything.
