Are you into zelda-likes or puzzles? I was looking to do a 1-2 week pixel art game in that genre and I specialize in pixel art.
I want to make a short game similar to this.
Currently I'm thinking about a game where you get turned into various monsters and it's technically not what the protagonist wants, but in terms of gameplay the monster abilities are useful to progress.
I have no idea if the game will succeed but could be worth a try.
