At first glance, the villa seems like the best housing. However, you can also get to 100 house quality with cutting-edge houses, and the description of the plant says that the residents will live longer. So it kinda seems like the cutting-edge house is still better, and that's a bit sad, considering the cost to build and unlock villas. The teleporters of the villas are also not needed, if you just intersperse the city with normal teleporters.
I played this game before and really liked it, but now that I have reinstalled windows it doesn't accept key presses anymore. It is really weird too, because it does accept the escape key to stop the level, and I can play the typing game in anti-idle, so it is not just flash failing. I would really like to play again. Does anyone know something to try?
