Press the left arrow key to go left, and press the right arrow key to go right. To jump, press (you guess it!) the up arrow key. If you want to go down lines, press the down arrow key (duh!). To go to the next level, press the space bar; but you have to be touching the door on each level. Beware of Goombas, Spikey things and more, but it doesn't matter as much because you have an unlimited amount of lives. There are 20 levels, but there is also a bonus level. Can you find it? Good luck!
Level 5 is rigged. Ignore its mediocrity. Levels 21-25 are not completed yet. The winning screen is after those levels. I had to add a script so that if Mario is falling below the last line, he would go to his original y position. It doesn't fix the glitch, but it compensates for it. Please press the love-it button. This is the best game I have made so far, and it is even better than my newest Attack of the Frogs. It is recommended to press the flag twice because if you don't lots of glitches may occur. Occasionally there is a glitch where you are walking and you are not on top of a line. Just use the level finder (press L) to start over the current level. Download this project for fewer lagging. Over 20 favorites and 50 Love-its! Thank you!
