It's a charming little game! Initially, I felt a bit frustrated, wondering if my gifts would ever land in the chimneys. However, I soon discovered the trick. The game cleverly helps by bouncing and centering the gravity around the chimneys, ensuring that the gifts fall right where they need to.

amazing!

Some Tips after more play testing and clocking it several times since its been uploaded. The sleigh is meant to be hard/slow to steer like a ship. with a tap of up or down it with make slow gradients in each direction. The turning left and right will allow you to turn around to do an extra pass ensure you although a bit of distance before you turn around to allow to another proper pass at your target. So make your you stay out of danger by watching your height level as you can still accurately throw presents or drop coal from higher up. This especially helps on levels with high slopes or houses on higher hills etc. Also be sure to look out for the Stars on levels that say bonus these are required to complete some levels and you can get the stars by dropping coal on them. 

So hopefully (if you don't rage out before seeing these suggestions) with a little practice you can complete the game and get the ending and a high score!

Thanks for playing
