Fun little game. Like the idea of the two characters having different specials.
Got stuck in level 3, jumping out of the hole. It felt I had to be pixel perfect to get out and it gave me trouble.
Yes that caused huge trouble for me when building the game. I used tile set colliders for the map. This made it so that sometimes when it looks like the player should be able to jump out, it hits an invisible ceiling. If you move one character by pushing it by another you will be able to be more accurate. Hope this helps! Thank for the review!
