Arrow keys to move. Use the strange type of ladder at the top of the screen to jump the spikes. By the moment I only made three levels. I will make more soon. If you find it very difficult press h to set the lives to 3 and if you want to be unbeatable mantain pressed the p key for 3 seconds.
Credit to everyone who has made any plataformer in his life. I made this game without creating any red blocks! (Sadly I don't know how to). Please if you liked it give hearts and stars.
