I really like the art style you've chosen, it's charming and well illustrated. The animations look pretty nice too! There's a nice variety of enemies and the combat felt pretty tight.
After a bit of trial and error, I was up and running, smashing trees over the head and dodging the presents, but it was a bit tricky to understand at first. There is some real charm here. I love that you put the effort into charged attacks working with level scaling and the upgrades is a nice addition to use your score for the limitation. Personally, I didn't quite like the sliding movement but it makes sense in the context of the environment. Great job overall!
