thank you for your feedback. how can i know how long a project is going to take before i start it? also right now im interested in making a game where the player has to travel by train to get to a destination but the train gets stopped for one reason or another and the player has to do some exploring to collect the needed materials to progress. like in mario odessy or jak and daxter. there will be 4 worlds in total and in each world there will also be an upgrade that enhances exploration. the first world will be fairy kingdom and the upgrade will be the ability to change size so that they can explore the buildings meant for fairy sized people. the second world will be elf kingdom and the upgrade will be the ability to activate elf machines and tools like blue eco from jak and daxter. the third kingdom is one where people ride unicorns and the upgrade is the ability to summon a unicorn at any time to ride it like breath of the wilds sheika horse armor. the unicorn is able to run really fast and double jump. the final kingdom is mermaid kingdom and the upgrade is being able to swim underwater indefinitely. the game will not have any enemies. the game is 3d.
