I am sorry to say that part 2 will be delayed because my mouse for my PC has been chewed up by my dog. When I get a new one I will make an .exe version and I need ideas for part 2 because I am very new to unity.
How about you make part 2 a platformer thing? Like there are just platforms and you can jump on them, also can you add more freedom with the camera? Plus, zoom the camera out, I can't see anything.
