I think some sort of skis to take advantage of the different terrain generation would be a nice thing to do.

Two other additions could go well if a tool of skis were to be added,

1.  A snowball cannon/crossbow (as to where snow falls under the cannonball/arrow to ski easier/faster)
2.  A javelin to do javelin things :D

I don't really have any resources at hand but I just wanted to get this (probably unprogrammable) idea out there

Getting probably-unprogrammable ideas out there? What're fans for?

Skis could be fun, and they could give a chance to take advantage of the new slopes. I have to imagine they'd be useless for combat; if skis made it in and work as we imagine they would, they'd qualify more I think as a non-violent way to have fun. I like the idea; it'd give an impression there's more to this weird world than pummeling monsters.

As for the weapons, I for one wouldn't mind either of those. Snow for projectiles or no a crossbow would be great. Right now projectiles are very spam-heavy; an alternative that's very powerful but shoots once at a time and needs reloading would offer a new gameplay experience.

As for javelins, by gosh yes. Throwable spears would be very welcome in this game.

Just wanted to come back to this to say that if a freezing system was to be added, the skis could freeze the water below you in the upcoming pond biome

cool
