Everyone loves the submachine series and this one reminded me of it. The bugs evidently aren't fixed. I just played this game and although reaching the top tower after using each shaped key and unlocking the different colors, I seem to be caught in a loop of finding the keys. I also see the blue triangle in the top bedroom, can click it and it disappears. In the outside view, there is a tunnel drawn that seems to lead to the center yard and there is a glimpse of that blue triangle at the end of it. After reaching that top tower and pressing the red button in the diamond level, nothing happens. Also, if you enter either of the two towers from the upper level, the only way to exit is to go all the way back down. If you exit the blue curtain in the bathroom, you simply reenter from the upper level of the bathroom. I would love to see how to obtain this mysterious fireworks ending. That having been said, these types of games are my favorite, so I am looking forward to your next venture.
