A video game idea I got from a dream!!!

Okay so there was this one dream I had and it was like a video game idea that was like similar to Homestuck(Peak comic btw) and it was like a 2.5D rpg game where these 4 Kids play a game that felt like it was virtual at first but then later on they realize there's a planet sale going on and Earth was for sale and the mayor was gonna try to pay for it but the currency used alien currency. The dealer said that there are a few buyers who bought earth. The kids thought of an idea to use the portal the alien dealer used to go and travel into the planets the buyers came from and murder the buyer... It's just a game right?? They later meet these people called Bugs which have like similar file type names and bug features. I thought of a character named Romeo Cicada which the rom part represents file ROMS and he was like this chill guy who wanted to have a cool music career but suddenly got dragged into the Bugs gang thingy.

I thought of the battle mechanic being like a mixture of homestuck, deltarune, and paper mario's battle mechanic. where you could walk around during the fight and its like 2.5D and you have to dodge the projectiles or like the enemies themselves. I thought of like the four kids being called: Shannon, Mike, Veronica, and Arthur. I thought of the game having chapters kinda like Deltarune. I also dreamed of like a final boss for the game too. The idea seems cool to me. I may or may not try to make it later in the future but i might since i have classes that could help teach game development.
