As a writer, I love what this game is narratively—like, just thinking about the idea that it's someone's job to throw snowballs down a mountain to discourage tourists from climbing it cracks me up! I'd love to see what you guys do in terms of a story, with the newspaper at the end of the level giving new updates/details every day.
The gameplay was fun, but I'd like some consistency with how much points enemies give. Instead of it being (seemingly) random how much they reward you, maybe you could get more points for beating them when they're lower on the mountain (like, you crush their spirits earlier but it's risky because they can still move and you need to consider your ammo). Or maybe you get a score multiplier the longer your snowball rolls down the mountain.
I think it'd be fun if there was more enemy variety too. I only got through the first few levels, so you might've done this, and it did seem like the pink climbers went a bit quicker. But you guys have all the solid mechanics there, I could see it being really awesome with a few tweaks!
