Nice game. Here are some notes:
- Font choice is excellent. Needs an outline though because it blends with other white things.
- Menu music is too low. Check if you're using the regular AudioStreamPlayer node and not the 2D one.
- The "Back" button in the menus needs to have a margin. It's too close to the corner.
- You went above and beyond in the Credits and being transparent about everything. Everyone needs to take note and follow your example.
- I'm not sure what the goal(s) are so I made my own. It took me I think 20-30 attempts to get the green/white billiard ball to hit the snowman.
Good try and keep it up.
