this is neat! I've seen the swap between worlds platformer concept done before countless times but the double jump and 2 choices really make it feel a step above most of the others. The visual of the colour choice prominently on either side of the screen, as well as on the character's head made it second nature choosing which way and let me focus on the level design (just a pity it was so straining to see as other commenter's said). Love the character animations and level design was great! Well done!
