About Stack PileUP
Stack the aliens on each other correctly and prevent them from falling.
How to play Stack PileUP
Getting started takes about ten seconds. You will want a keyboard for this one — the arrow keys / WASD carry most of it, and the table below has the rest. The game runs in portrait, so on a phone you can play one-handed, and on desktop it stays centred rather than stretched out of shape. Expect the first attempt to be a write-off; that is normal here.
Controls
| Input | Action |
|---|---|
| Mouse | Navigate menus and interact |
| Arrow keys / WASD | Move |
| Spacebar | Primary action |
On mobile: Tap and swipe directly on the screen. The game is built for portrait, so you can play one-handed without rotating your phone.
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. The result is something you can pick up cold months later.
