About Space Tower Defense
Tower Defense is a strategy game where the player's goal is to protect their territories and the main tower from enemy attacks. To do this, the player builds defensive structures along the attack trajectory, the strength of which depends on the cost of energy that the player receives for defeating enemy equipment.
How to play Space Tower Defense
The opening minute doubles as the tutorial. The controls are listed in full in the table below — there are only a handful of them. The game is wide rather than tall — fullscreen is worth it on a monitor, and on a phone the picture is much better sideways. Restarting is instant, so there is no cost to experimenting.
Controls
| Input | Action |
|---|---|
| Mouse | Select units and place buildings |
| Left click | Confirm placement |
On mobile: Tap and swipe on screen. Turn your phone sideways — this game is designed for landscape and fills a horizontal screen.
Why it is worth playing
The appeal here is the loop: a short round, a clear result, and an obvious idea about what to do differently next time. That is a rarer quality than it sounds.
