Haha sorry I didn't add a tutorial. This game was an assignment for one course in University. I made it with Unity, I thought it took me 50-70 hours in total, and I was not good at Unity at that time. It was 2 years ago so I can't say it clearly. If you are good at the Engine you are Using it won't take long to make such a simple game.
Damn, it might take me a while then. I'll try to keep the game somewhat small, maybe with a 1-month limit.
Yeah, I probably should keep the game small. I wanna make games as a hobby, and I don't want to spend hours a day on something that I won't enjoy. I will try to get at least 7 hours a week of game development time.
