Yanniboi said most of it but yeah it was fun and functional. It was pretty simple but done in a clever way for what it is.
Echoing a lot of the same feedback points, the win condition wasn't clear but I did end up winning. I just found the border and walked it until I found the building. The spawn position for the top snowman made it a little tough to hit just because of how it works but it wasn't impossible, just had to get a lot closer than the others first lol.
I think either making them move faster or making them spawn faster over time would be a good way to amp up the difficulty, or both. I didn't end up losing any health in my time playing so difficulty wise it was definitely on the easier side.
Great job though, glad you finished and submitted something.
