Thanks for giving my game a go, and thanks for the constructive feedback!
Yeah, I missed out on updating Santa’s speed when the game speeds up. I guess in the process of trying to get the game out, I overlooked that. I think editing Santa’s hitbox and speeding him up would be fairly easy to do, now that I think about it, since I already have the gravity of the presents (and some other things) being affected by the speed of the game. I will see if I can make an update once I figure it out!
