Will you follow the theme? I think i will to make the challenge harder (very new to gamedev)

Yeah! For me it's what makes it fun (and it can also lead to interesting ideas)

Yes, In fact i already Invision what the Game is gonna look like

Yeah I will try to follow the theme as it can bring up interesting ideas and gameplay mechanics

I hope the limitation meshes well with the theme. I don't know about simulation "without physics"

for simulation, it doesnt have to be a physics game, it just means you pretend to be something, like, bird simulator where your a bird if you are new to game dev, its easier to make games with limitations, because theres a clear goal, but if theres no limitation, the game will seem like it was made in the brink of time with many features not fully polished, in the beggining of your career, less is more, until you are familiar with this, then scope larger maybe even starting your dream game.
