uhhh, here are some ideas: an RPG game or turn-based battler, an animation, something cool with pen, follow griffpatch’s mmo tutorial, something with Python and TimMcCool’s scratchattach, a story-based platformer with an interesting mechanic. Also, when you’re looking for ideas, you might want to scroll through game jams on itch.io because they usually have themes that might give you inspiration even if you don't enter them.
