its going to take me at least 1 or 2 weeks (approximately) to make this game. I cannot make promises because I don't have all the resources needed for the complete game but yes I can still make a demo or playable build of it with the stuff I got for now.
You don't even need a build for the Devlog forum. Check it out, and see what people put in theirs. Often it's just a screenshot, gif or something.
Also, now I look- there is a Game Development forum.
