Hello! Thank you for playing my game! Sorry for not answering earlier, I was taking a break from things.
- The first issue, about getting damage when exiting any menu, it's fixed! I just updated the game.
- Also, you can eat but it's a bit clunky. And it's a bit tricky to fix. For now you got to look at a block and then right click to eat.
- The render button is there but I didn't give much explanation about it... it's there, but only when you're playing in wireframe mode, due to free memory/space.
