QuestHub play guide

How to play

Objective

Stop all 20 waves before enemies take all 13 units of elemental matter.

Controls

Click a non-path tile to open the build menu, then click an Earth, Water, Air, or Fire tower you can afford.
Click an existing tower to inspect, upgrade, or reclaim it; use Play to start or pause and ×1/×2/×3 to set speed.

Your first move

Before pressing Play, click an open tile near a long stretch of path and choose a tower after checking the next-wave colors.

Practical tip

Each tower deals bonus damage to one element, so use the next-wave preview before spending fragments.

Testing note:In Chrome, verify that clicking a buildable tile opens the menu and that Play advances the first wave.
