I love the presentation and concept of this game! The combination of character design, particle effects and music all worked very well together. The inclusion of things like a leaderboard, tutorial and settings make the game feel pretty complete as well.
I must admit that the rules of this game weren't very clear to me, though. Even after getting second place on the leaderboard, I still don't know what actually causes the Game Over screen. There were also some slight peculiarities such as the bullet being blocked even though the path was clear, presents that were supposed to be fired getting stuck under the sleigh / other presents, etc. But nonetheless, playing this game was actually really fun! So kudos for making a game that's fun enough to not frustrate when it doesn't work quite as it should.
Oh and I accidentally messed up the leaderboard by entering a name that was too long, oops I guess.
