I am glad you liked the game and I so appreciate the bug report! 
So I did notice a lot of issues with the Rigidbodies and Colliders in this game and after countless attempts to resolve those issues of flying or launching the player, I just couldnt figure it out. And I couldnt think of a way to phrase this issue for StackExchange or other websites so I really was kinda sunk. I do want to experiment with this movement and controls in the future to prevent the wonkyness but I at least have a great time with it lol!
Also I originally was going to use more of the push boxes and then I noticed that that could cause much worse issues with players being launched just from one so I decided to risk it with only one crate and thankfully, it didnt cause much issue but there is definitely some more to learn in the future!
