Arrow key or WASD to control mario. 1 to make TNT's. As this control is very janky, it is not very useful. You often just spawn in TNT's you don't even have them if you hold the 1 key. You also can use the mouse. Please DO NOT abuse the mouse. JK. You can abuse the mouse.
I made this like a few years ago. I think I made it near the start of my senior school years. Year 4 to be exact. It's been a while since I renewed it and the newest thing I added was the spawn goomba button. Also very janky. :/ Free to use any code in this. It'll be nice to see some remixes.
