Thanks a lot ! Once before going to bed I just had this idea in my had. The next day I woke, and started to make this game. It was really easy to develop, but I spend a lot of time to polish it and to balance the difficulty, to make it not so hard, as my last game Intense Sleep, so everybody can complete it. I can spend from 3 to 4 hours a day, changing small things, but the main development time takes about 3-5 hours
