Super Swap

Hello Everyone, this is my first post, but I have read a lot on here.

This is a game I have been working on for a little bit recently, there is still lots to add, but I hope you enjoy it.

Controls: WASD or Arrow keys to move. At random intervals the keys will swap, so W will go forward, but after swapping will go back. Red tiles kill you, purple are stars and the gold is the finish.
When you finish a level, press escape to go to the next one.

Please let me know what you think and if you have any ideas / improvements.

Thanks, Max
