Welcome to "Invisible Jumper", a pen platformer. There are 10 levels. You can't be seen when you are moving up or down. NOTE: Level 9 is EVIL!!! Arrow keys to move. Red is lava. Yellow is bouncy. Can't jump on orange. Purple moves you left. If a level is too hard, [s] to skip.
Thanks to @Spidertest for the pen text engine. Thanks to @superdognumber5 for level 7 (I modified it a bit). Thanks to @PackersRuleGoPack for the idea of an animated thumbnail. Thanks to @PullJosh for his amazing platformer tutorial.
