Thank you for the feedback! This project started less than a year ago; the first couple weeks were spent prototyping the movement system. I wanted to make sure the jumping, climbing and swimming all felt perfect before I started working on anything else. I went through many iterations, most of which felt clunky and terrible. Some interesting ideas were ultimately scrapped; I had wall-running fully implemented, but was taken out for the sake of simplicity and user-friendliness. The project was on hiatus for about 6 months, due to real life circumstances, but I'm back on track and have been working on this daily since October. Thank you for your concern, I know Nintendo is notoriously strict when it comes to their IP's. I've taken down the videos from the Prototype and Alpha builds for now, as those still featured placeholder sound effects. The sound effects have already been replaced with commercial free resources in the most recently uploaded Beta video. I'm currently using RMMV for the updated frame rate and performance over RMXP. Some of the assets being used are from RMXP, but mostly as place holders.
