Thanks so much for the feedback, I really appreciate it. I'm going to be re-iterating on the idea and releasing an improved version of the game in a few weeks. Some things I'm going to be adding: better looking sprites and tilemap with some basic animations, music and sound effects, WASD movement, a UI for a title screen and win/lose screen, and a mechanic to make the player sprite larger and your snowballs do more damage as you gain more snow strength, and a mechanic that increases the monster's speed and spawn rate as you kill more monsters.
