Close the Window!

Close the Window
You just installed the new OS, called Ruindows. It worked well for a week but suddenly some erros related to this version started to popping up on screen, you need to close these errors before it's too late!
Every time you click on 'start' there's a slight chance to invoke the farm mode!
It features:
1. Upgrades
2. Various errors appearing on screen
3. Farm Mode
4. Cool SFX's
How to play:
Use your left mouse button to click on the windows and close them, use the upgrade points to spend on the upgrades!
During the gameplay, press space when the time comes to use your super closing window power and destroy all the errors!!
You can pause the game any time by pressing the escape key.
Observation:
Steam Trading Cards will be available once the game sells a bunch of copies, so please, help!
