Hard 2D Platformer

Hello everyone, welcome to the Architect's Dungeon! This is a 2D platformer that is a bit of a brain twister as you play between two dimensions and three different players. As the game develops, you will face more and more difficult challenges in each of the levels culminating in a test of everything taught by the game in the final level. Will you successfully complete the challenge and escape the dungeon? Good luck!

W A S D to move and jump.

Q and E to switch dimensions.

Left and Right arrow keys to switch player.

Some questions:
Is it too difficult? Should the movement of the players be easier managed? What would you add or remove?
