I love how you used simple graphics to make something really charming! The squash and stretch of the characters moving makes movement feel quite lively!
Unfortunately I did get myself softlocked while playing your game when I got the squash & stretch guy back down into the chasm where I found the bomb guy and I got the bomb guy into the room with the jump guy. I couldn't progress because I needed the squash and stretch guy to free the bomb and jump guys but I need the bomb guy to free the squash and stretch guy.
