Thanks for this question.
[SPOILER]
So, when i created this game i thought abount the feeling of learn something or be exposed to something new, the black world represents our unknow abount the subject, and the little flowers represents the small progress we have in this process of learning.
The crystal was like a "checkpoint", something that represents a award in this new subject of studie like when we finished a project. The secret portal is the end of game, is when are show our time in game, that is like the time we pass to feel confortable in the subject.
Every time you find the portal, a new random level is created, that is like a new subject, something new, something to be discovered.
Unfortunately i was not able to translate this idea to the game. Hope learn with all the feedback i received and make a better game in next game jam.
Thank you for play.
If you find this text kind of weird, i was using google translate. 😋
