Window cleaner vs birds

CONTROLS
Move - WASD or Arrow Keys
Clean Windows - Spacebar

Nothing's permanent!

Especially not that nice shine on the windows you have been cleaning all day. Pesky birds! And even the very rope you are dangling from is about to tear! (we only had two days, there was simply no time to source proper safety equipment, sorry..)

Use WASD or the arrow keys to move about the building and get wiping with the spacebar. How many windows can you clean before the final strand rips?
