Nice game!
Reminds me of a few old early 3d games can't name them for the life of me though.
I looked at the instructions briefly before playing the first time but still managed to play like a numpty the first time flying through the green and yellow rings as well meaning i got penalized.
Second time i worked it out though and had a bit of fun. Nice touch on Santa getting stuck in chimney lol! i thought he was proper stuck or game glitched until i realized to click him with the mouse to the bottom.
Other things i liked soundtrack or title screen was nice and cosy too. You did a great job with menu layout and good instructions once i read them properly the second time lol!
Only nit pit if i had to had one is what others have mentioned was the difficulty is a bit hard to maneuver into the rings consistently as. I imagine it is a learning curve however as i improved greatly on the third attempt playing and got 2 deliveries lol! yeah only two but was a start right.
Good job overall!
