Horrible Platformer

Please read this...
This platformer is possible. Use arrows to move around. It's more of a test than anything. It's made for the mechanics. Not to be taken in account as a game but more a base for future games. 

When you get to the end of the stairs, jump and land on an invisible block (to do so jump as far as you can)

If u fall, please go back to the starting platform by moving to the left.

If u were to want and try speedrunning the platformer, please start at the uttermost right side of the starting platform, on the left side of the game. 

WARNING : There is a roof. You may bonk your head on the roof (this is wanted). Hitboxes are square. I (Ttree) only managed it in seperate parts when testing the level. I have never completed the game in a go.
