you have to jump at first to start (sometimes) arrow keys to move glitch free (mostly i think) you can wall jump and climb on ceilings
all by me only 22 blocks - and no green flag clicked or forever blocks! the player moves kind of slow... i could fix that but it would take blocks fine two blocks but it's still a platformer engine if the player is a snail if you want it to go fast[er], then you can [alt-click] the flag but you can only do that if you have Scratch Addons, and enable "60FPS project player mode" on the addons you can download the extension here: https://chrome.google.com/webstore/detail/scratch-addons/fbeffbjdlemaoicjdapfpikkikjoneco?hl=en i swear its not a virus
