Copyright rules

I'm curious about the copyright rules, as I'm trying to make a game, and I want some info whether or not I would be safe doing these things: A: Hollow Knight port Hollow knight ain't on 3ds and I wanna change that, but I'm pretty sure I'm crossing the line. B: A port of spelunky classic Spelunky classic is free, and I think this should be fine, but I'm not sure C: A meat boy CLONE Let's say I make a meat boy clone,, but physics, level design, and graphics are different, but still at the heart of the experience(hard levels but unique twists, similar physics but different), and my character is orange, and looks more like that thing from jumper(A square with two tiny legs, two eyes, no arms) I think I'm safe here, but still would like to be reassured Thanks in advance!

SmileBASIC will remove anything that they feel infringes copyright from their servers. Other than that, I think you're free to make whatever you want.

So so you think I could get away with the spelunky classic/Meat boy clone?

Yeah. Don't become upset if you upload to the Smileboom servers and they take it down, though.

Ok, thanks! How do I lock a post?

I think Yttria could do that, but I don't know how either. By the way, Tarudahat, some others, and I are currently working on the Bomberman 3DS title, known as Super Bomber Blast. Have you downloaded it yet? If not, here's the link: http://smilebasicsource.com/page?pid=1302

Have not downloaded it yet. I will when I get home. There is also a celeste classic port apparently.(I have the code in my pico-8 emulator post)

The Celeste port got explicit permission from the creator of Celeste. Clones are usually okay, trouble happens when you use copyrighted names and assets. Even wordplay on names and parody of likenesses.

So would calling a meat boy clone 'slime guy' be ok?

You can make a literal copy and just change the colors of the characters and it shouldn't get taken down. Maybe change the name a little bit but i'm not sure about that

Nah that isnt right, the character looks more like that thing from jumper

Its not really the original characters that I want to use, I can easily replace them(my profile pic is what I'm using for the meat boy clone), its the gameplay that I'm really trying to clone(besides spelunky classic, which is freeware)

Oh, then you should be fine if you upload it.
