excuse me please tell me how long the game is, I just got the map, how many more worlds are there to go.

and can you tell me how to get the blue and red key, unless it is a HUGE secret

Edit: I am now playing the game again (after about 1 year) and I think I found a bug. On Browser mode, if you go into the first Hay Hay Land room where Veu leaves and then go back to the previous room and then go back into the Hay Hay Land room, it freezes (can't move). It happens even if you do it again after you already killed him. And not just if you enter it from the left side, but even if you enter it from the right side while backtracking from Electric City. In other words, entering this room more than once = death.

Oh yeah. And I still didn't find the blue key. I looked everywhere. My best guess is that I permanently missed it or something.

Also I suggest making Guardian Star buyable. I have too much money and I would love to avoid enemy encounters.
