this is so cool! I love the moving the mouse mechanic to interact with objects, I am wondering how you would implement the 3rd dimension to this, hopefully it's nothing too difficult, the walk cycle is great, and so is the run cycle. Honestly would want to know more of this.
Please take your time, since this project is probably out of passion for horror and Undertale. I love the original comics too, so if this ever gets finished, I can't wait to use my knowledge of the comic for this game haha.
