Hey, I enjoyed this! I think the art looks really nice and it fits the vibe of the game jam perfectly. I just have a couple of comments!
1 - It seems like there is an invisible wall/object in level 3. I have to jump over it in order to proceed in the level.
2 - It also seems like the presents are moving too fast for me to clear level 5. It might be that I am bad at video games, but I think it's more likely that the speed of the presents (or the main character) is not tied to physics process of the game engine and might be different on each computer. I know this is something that happens in Godot, but I don't know if it happens here!
Let me know if you get (2) patched, because I'd love to try out the rest of the game!
