I forgot to describe my idea. (ERM.) So, the idea is : a reptile person in need of energy brought by heat. The heat can come from hot beverages (obviously), the sun, UV lamps, steam, radiators, or just being in their bed. And they need to do stuff with their days, because productivism and all that, but without burning out. (The only problem being that I just have this idea, and nothing else, because I can't do anything.)
You actually can do things, don't put yourself down! You already came up with an idea all on your own, you can handle it!
Anything you don't know, you can learn.
If time is lacking, just reduce the scope of your project to only one or two elements to demo your idea.
Hop onto paint and a construct 2 tutorial or someting similar and see how far you can go :) Heck, just make pixel art of your reptile person or something, it is not easy but it is attainable!
