Small 2D game where the player completes platforming levels to collect eggs and avoids various obstacles including enemies, crushing machines and bottomless pits. The player can also take control of different vehicles, currently including a submarine to travel underwater areas to unlock new areas within levels.
I knew that each level end flag had it's own variable for setting the next level the player will load into. I made levels quite linearly with only one end. Having multiple endings is as simple as dragging more than one flag into the level!
This way, I could have the player enter levels based on difficulty. If the player falls to lower parts of a level, they may end up going to an easier level. IF the player completes a hard route in a level, they may be given a more challenging level!
