More concerned about possible wind physics if I decide to include that, and also how much depth it should have. May have to stick to a strict number of gameplay hours. I'm imagining some promising ideas though, such as you plant a seed and wait, it rains and then it's sunny, you can watch it grow and collect it for in-game coins or something, but watch out for the snow cycle as it just kills all the plants so you will need to wait again. I'll probs start off very simple and then see if it expands into needing the inclusion of characters that want items and such, like quests, or if it's just a linear puzzle game. Second one is a lot simpler, kinda like Limbo where you just walk through the game. First ideas would have some adventuring, quests and would be a lot more detailed and it might not need that. I also thought of what would happen when you go between areas and maybe yes some puzzles would need you to cross a few rooms at once. A key gameplay idea is going to be how it affects the player too, I thought windy means he flies away and you 'die' so he has to be grabbing something, adds some urgency, or perhaps it doesn't affect the player at all and only things around you. So much balance will be needed!
