Great submission for your first gamejam, congratulations on finishing!
I had no issues playing, so great job having a complete experience.
If i had the chance to tweak a thing, it would be either to have something like a little arrow indicator (like a compass or so) to give you a rough idea of the next direction. It's hard to memorize the locations/orientation since the platforms all have relative similar dimensions, maybe thats another way to improve there to make some smaller and som thicker platforms to recognize patterns as you move along the level.
Adored the little captains move-animation and the fact, that the outer borders of the game is equal to the color of your theme page, sneaky ;).
I had fun - thanks for the submission.
