For sure. As someone who isn't overly creative when it comes to plot, I'm not sure I can really help you with that, but if you have questions about gameplay and stuff, I might be able to help. It seems like (from what you've said) that you are looking for a faster pace game. Are you thinking like a bullet hellish kind of thing? More puzzle based? More strategic gameplay? Or a mixture of all of them? You have a metric fuckton of options with this, and with rogue-likes booming like they are, you have a good chance of doing well for yourself if you can make at least a decent foundation for a game. If things go well and at any point you feel it's polished enough to be put out into the indie community, send it to a youtuber named Rockleesmile. He does reviews of indie games and has a good deal of experience with rogue-likes. Hope this helps :D
