Hey!
Looks like a nice little game, but my RED game has been around for quite some time and will be release physically later this year... Also in this context the name is a bit more appropriate ;) Don't mind if you keep the name, but could be nice to not have the same.
(even ported to Amstrad: https://krakendev.itch.io/amstred)
If down the line the game needs a different name then I may change it. Though RED is not exactly a unique name, a quick google search shows a few fully released games also being called RED.
Perhaps RED GB or GB RED would be more appropriate. The GB Color version I'm planning on adding on at the end would have very red graphics, as the game progresses the graphics become more and more red until you are facing the cults god and everything is entirely red.
Agree it's not the only RED game around, and these being "just" homebrew games I didn't even look intro registering a trademark. I don't really mind if our games have the same name, but it might be a bit confusing and we can probably be smart about that :) Another option could be to add a subtitle to differentiate them. I was considering something like "RED - Against the Machine" at some point.
Cheers and good luck with your game :)
