The idea itself is quite cute. But sadly I had a few issue regarding the controls because I dont have arrow keys xD A and S works for walkinf but W doesnt for Jumping and it feels a bit off that I cant shoot while walking because walking is what I have to do to keep the momentum. I also didnt get how to pick up presents I just did sometimes on accident and I feel like i need to press something but I didnt know what.
I think you should try to make a build that´s playable in the browser next time, because without the bugs the idea is sweet and fun but people just tend to not download demos in game jams. c:
