2D is definitely easier, and I would not mind at all of a recreation. I made the demo in about a month with a lot of slacking, so it will probably be easy lol
For this game it is just a bunch of my face that I messed around with lol. Photomosh has a webcam feature and I just tweak the settings a lot. For some assets it can work just to take pictures and Photoshop them, you don't have to necessarily be an artist.
