I did have one bug I encountered. I think it was around the second or third save or so, just before you jump into the water to swim for the first time. I saved there and then left it on a long while listening to the music and got busy talking with one of my friends, and later quit the game, then when I started it up to play some more a few hours later, I had a very weird bug where any time I jumped, I would decend very, veeeeery slowly, and I could not double jump, or climb the ladder. I had to restart the game to fix it.
No idea what caused it but its probably something you should look into, it could be game breaking later. Right now its hardly a big deal because the game is literally a minute long so far, but later on, it could pose huge problems
