I really like your concept of the game! Getting together to a certain place. Also the art of the character and the background/tiles are amazing. A lot of detail in the work. Keep it up!
I suggest to that you make your 2 characters diffrent in the way they move or let one player start from the right and the other one start from the left side of the map so they meet each other in the middle because right now it is like you have to move through your parcour two times the same way what makes the playstyle a bit one-sided. Also if you jump with the player you are not able to control it in the air what leads into difficulties on certain challenges in your map or if you collide with an edge of a tile then you are just stuck and drop down again. If you improve that I think this is an amazing game.
Good Job!
