Thanks for your feedback!
The game was a bit rushed so it could be released for Christmas. You can't use the other abilities because they're not in the game yet :P
I will adjust the walking sound. I actually changed it a few times but still wasn't 100% happy with it. Leaving it with no sound feels a bit empty, I'll see what I can do :)
Same for the ending, it's all I could do in this short time span. Allowing you to go back could make things confusing for other players too like they don't know if the game actually ended or not. There's not really a perfect solution until I finish the game.
Speaking of finishing the game, if you were left wanting more, come back in a few weeks :)
The characters will have new abilities and Santa will be able to use items in battle, like special attacks, and the game will be longer to accommodate all these new mechanics in a smooth learning curve.
Thanks again!
