This game was really fun. I like that the the gameplay kind of drove the story more than anything and the text was short. It was a nice change of pace after playing some dialogue heavy games right before (not that those weren't great too!). The shining aspect of me for your game though was the main mechanic. Very unique and an interesting way to setup some cool puzzles. I would recommend in the future not binding the escape key to anything for a webgl build as it minimizes the screen and can break the immersion of the game. I didn't do any pausing and it had zero effect on my enjoyment of your game, but just thought it was worth mentioning. I'm gonna definitely have to agree with some of the others on the checkpoint thing. It was pretty frustrating having to go back to the very beginning of the game. Especially considering the first chapter you are a slow baby and old man. Other than that though your game was great. Good job!
