Really cool concept, and the drawing mechanic works well. Having left and right mouse button act separately, almost as if the player is controlling unique left and right hands was a good choice. It's pretty satisfying to scribble around the screen, and has a pretty neat etch-a-sketch vibe going on. The intro letter was a great way to set up the lore but there definitely needs to be some kind of gameplay intro/tutorial and some more player visual feedback. Am I supposed to use both left/right ribbon in a symmetrical manner? Can I draw the ribbon however I want as long as I hit the specified vertices? Do I get a higher score by using the least amount of ribbon as possible? Some clarification on these game mechanics would go a long way in the overall experience. It could also use some sfx, background music, and some Christmas-y visual flair. That being said, I think you have a truly wonderful prototype here and there is some real potential in the drawing mechanic. As a GameMaker noob (a little over 1 year experience), I'm super impressed at the unique mechanic you were able to develop in just one day. Kudos! I had fun messing around with your game, and if you do continue developing it, I would be curious to see where it ends up. Keep up the good work!!

edit: You should check out this jam game called SEW-Tastic https://mech-mind-games.itch.io/sew-tastic with a somewhat similar sort of core mechanic to maybe get some inspiration for your own game, if you want

Really interesting control and game concept. Definitely not complete but the start of something quite interesting.

Nice job making something unique.

Good game! Add bgm   and it will be fun :D
