This game is a roguelite deckbuilder where you explore a post-apocalyptic world, collect cards and artifacts and fight enemies. **Try to stay alive as long as possible!**

**Lets start with some keyboard shortcuts**

- *ESC* - Open the menu where you can see your cards, artifacts, ... or abort choices
- *SPACE* - End your turn
- *ARROW LEFT / ARROW RIGHT* - Select card or enemy to hit
- *ENTER* - Confirm your choice
- *X* - If you hover over a enemy and press X, you can see more infos about a enemy
- *S* - Open player status

You can also use the **mouse** to select cards, enemies and click buttons.

**Cards**

You have a deck of cards that you can use to attack, defend or apply status effects. You can see your cards in the bottom of the screen. All cards cost action points that reset on each turn. Use them wisely!

**Combat**

If you press Continue you will fight a dummy enemy. See if you are able to kill it!
