Clicking on the "items" vase in the UI can create lots of "inventorium" screens if you keep clicking the vase.
Reached the Robozone, also managed to deliver some boxes to some of those girls next to the ladders and even did some minigames to unlock the stuff keeping me down.
If you click in some items like the maid dress and then press ESC, the ESC menu is behind the other menu.
This game has some neat ideas and a nice art direction but it also gets frustrating since most of the time, I just get slowed down by enemies.
