Well, that was a surreal experience! I don't know what to say besides that. Funky.
Possible bug - is the Obelisk supposed to do something? Its pop-up suggests that it is supposed to generate money, but while it glows to varying intensities, it doesn't seem to do anything with it. Also, they behave weird if there's two of them activating simultaneously - it's as if there is a global charge-up value, and with two of them, they both charge up half as much.
