Can't believe it's created in 48 hours! The puzzles are so well designed with awesome mechanics. Just a minor suggestion, as we only need to use the keyboard for control, that'd be great if we can restart the level with the 'R' button or even better if the level is going to automatically restart when there is no virus left in the scene. Sometimes I find it not so user-friendly to move my hand onto the mouse and click the restart button. (Becoz I died too much x_x). Excellent game indeed!
