Multiple Bugs

Sleeping in a bed creates glitch where the day comes around, but you're pushed onto the floor and can't escape the "Leave Bed" screen. Pressing esc doesn't work to close it, so you have to close the launcher.

There is no sound when the player is hurt. Fall damage, fire damage, mob damage, anything.

Once the player is on fire, it continues to take damage, but there is no fire on the screen to signify that you're on fire, and also the no-sound-when-taking-damage bug plays into this if you don't realise you're on fire.
