Alright, it's no coincidence anymore: this is a ripoff of 12 Magic Orbs. The world themes are similar, the stars are literally the same order as the orbs, and the level concepts themselves (especially World 3) is literally the same as 12 Magic Orb's World 3. Hell, the terrible overworld you made is LITERALLY structurally created exactly like 12MO's overworld. At this point, I won't be surprised if you tried to ripoff the submaps too.
I've been watching in the background for a while, and at this point I've had it with you (and I don't even know you). Seriously, this just baffles me that this just looks like a ripoff of something far better, and I'm more surprised that G.D. isn't more insulted. This isn't just a situation where someone tries to ripoff someone elses' style (Choconilla Rise, anyone?), this is stealing a hack concept without much originality and executed poorly.
I wouldn't be surprised if A) you're making this hack to troll GD, or B) you love 12 Magic Orbs so much that you're making a hack shockingly similar to it. I wouldn't just redo the overworld, I'd literally
start over the entire thing if I were you. It's hard to restart at first, but once you do, you'll feel better about yourself in the end. Don't let your anger be thrown at us after you read what we have to say, otherwise you'll make yourself look bad, and when submitted the mods WILL reject it. If it does get accepted, people will continually call it a ripoff and you will
never escape from it.
Save yourself from this trap before things get REALLY ugly for you in the future.
