Unfortunately not finished. This game is a idle sim that has you handing out presents to slimelings from Santa. However in its current version there are infinite presents, so no particular challenge. It's unclear what you're spending to upgrade your tree, but you can upgrade it occasionally.

I understand that, those are mostly bugs. I'm just waiting for Liam to reply to know if it's ok to update and fix them. I probably only worked on it 2-4 hours per day, because of school, which is why it's in this state. I spent most of that time working on the game and not looking for bugs. The happiness to spend on the tree upgrade is supposed to be displayed, seems like a html bug again. Thanks for the feedback.
