Pixel art platformers are easy to make and have the capacity for timeless fun. Try not to be too harsh. My kids drawings are crude but I appreciate them for what they are to me. Games and art I made as a kid and teen were also mostly for fun.

While it did cross over to excessive at some point, I learned and moved on. Now I'm not living the game dev dream of my youth but enjoying an easier life as a boring programmer/manager. And I still enjoy simple and complex games alone and with family.
