Summary

for #3 tasks 5 and 6:

- If the answer is correct, the score will be increase by 1.
Fixed the health system / heart
- The heart icons will be reduced if the answer is incorrect.
Game Over Screen

I added a new panel that appears when the player has no remaining lives.
- issue: the character and tiles are in front of this panel
Level Completed Screen

I also added a new panel that appears when the player completes the current level.
- issue: the character and tiles are in front of this panel
Unlocked and Locked Levels

Julius and I have agreed to lock the other levels, unlocking them only after the user completes the current level.

UI
Main Menu I changed the sprites for this menu only using the provided game assets. This can still be modified.
Game Scene I included a label above the question to indicate the player's current level.
