Yeah ok. I felt like trying to create a few tiles myself. A snowman or a christmas tree.
Can I share a few (realistic) ideas ?
As a "clear screen" weapon, there could be snowmen near the sidewalk and Moya would grab their heads and throw them in the air before they explode and all the drones on screen are destroyed.
A few pngs could wait for her, holding hot chocolates that would refill her health, or stamina (because it's cold outside). It'd be nice to see her drink a hot chocolate.
And finally, as it is said (in the nicely written story) that her goal is to get the gifts back at the bottom of the christmas trees, Moya could have a carry limit of 50 gifts for example and she would bring them at the bottom of Christmas trees to reach the goal of the level, and the gifts would appear at the bottom of the trees.
Anyway, keep up the good work.
