Hi D!
Love the colour theme and thought put into your scene and itch.io page. Your reindeer is super cute and I love the effort you have put into him. Also love how you've made the page header look like its part of the game, with the snowflakes looking as though they will fall into the scene.
Constructive Feedback:
Outline of the buttons are a bit fuzzy and faded, unsure if this is a style choice or not.
On hover effect makes the font very hard to read for the white to red snowballs.
Other than that, very well done!
