Just tested it out, this engine seems to have a lot of potential. Probably the most annoying thing I encountered in the game is the lack of pressing a button to run. Sometimes I would like to pace myself in a level and go through it much slower than I am forced to currently go. If I walk in the same direction long enough mario runs REALLY fast. I don't want to feel like I'm forced to go for a speed run record when I know I will just die all the time. I hope you can refine your movement for future releases. Other then that I hope you can continue the good work
