This game is actually genuinely fantastic. I do think the beginning starts of a bit slow, and obviously more "enemies" were intended judging by the name of the upgrades, but I genuinely really like this game.
Some of the art could probably be touched up, since the contrast is really harsh in some places and really subtle in some others (brick vs background and snowman vs ground) but I genuinely love this game
Sound design is interesting, but never boring
Visuals (in terms of art) are just fine, maybe adjusting how it contrasts against the background
Solid gameplay loop, but that kind of comes packaged with incremental-style games so it doesn't need to be commented on further (doesn't mean its bad, gameplay loop is fun, but obviously there isn't much there from jam time limit)
I feel like the game would benefit from pacing changes and more visual effects to keep the player entertained throughout the whole game, since the beginning is a bit annoying to get through
One last thing is that i think the snow decreasing over time should be changed to just how much you move so you're encouraged to optimize every aspect. Time based stuff like that isn't my thing to be honest. Although maybe I'm wrong and its just because there isn't much else to focus on.
Overall, yeah solid game, would recommend 10/10 in every aspect (but maybe originality is lacking a bit)
