Definitely put me in the Christmas mood
The Good: First off you did a fantastic job on the music, I like that it was Christmas theme, Just like Mario.
The Bad: Only three types of enemy's, Levels don't really change, "New Game" mode is WAY too short, "Combo" mode is a bit boring, I didn't feel like I was completing a level just playing one long one.
Suggestions: Make an elf that is like Luigi to Mario's Santa, Needs more levels, Levels need to be different, Make a power up that makes his suit turn blue and makes him throw snowballs (like the fireballs on Mario world), Needs more modes.
All in all this game has a lot of potential but call me when the sequel comes out.
