Instructions needed for non-obvious hci mechanics.

[TrickQuestion]

I didn't discover You Monster until looking through the code, because nowhere was there any indication of how to sell something (nor the sale cost). I was actually pretty surprised that right-click worked. There needs to be hovertext or a [?] thing or something available to explain game actions which are non-obvious.

You can also shift-click to buy or sell 10 at a time. Technically speaking, proper UI design demands that we expose buttons that the user can click to perform these actions, because on a mobile device, you can't shift click or right click at all. Once we have buttons that perform these actions, the buttons can have a tooltip that says "you can also sell ponies by right clicking on them" or something. Cookie clicker puts these buttons below whatever building you are hovering over, but this still doesn't work for mobile and it's really frustratingly unreliable because the buttons keep vanishing while clicking them. If someone has UI suggestions for this, it would be appreciated.
