You're Mampfred, the only remaining citizen of Dwarf City. The others left when love-crazed princes started attacking to steal the singing and tingling tree. If you could could only find a way to stop them.
Well, there is one. If you can keep the tree alive for about 120 seconds it'll grow to a huge tree, too big for princes to carry. May then even your fellow neighbours will return home. Without the tree all hope will be gone.
You need to keep the tree alive for two minutes. To reach that goal you need to cultivate the little tree by fulfiling it's demands and protecting it from the princes.
The tree tingles when ever it has a demand. It then shows what it needs. For a speech bubble simply talk to it. For the watering can and scissor you need to pick up the right item and use it with the tree.
The princes can be kept away from the tree using the traps that lay around in Dwarf City. Just make sure they are armed.
