Depending on the opponent selected, a match consists of anywhere from 2 to 8 rounds.

Defeat an opponent by making its heart level to go to zero. You cannot directly attack him with shots that you fire, but you can use hazard and enemy cards to cause damage.

Special rule about early damage:

In the first 30 seconds of the match, all damage received by players is reduced to 1/3. During the next 30 seconds, all damage received by players is reduced to 1/2.

To represent this damage reduction, the screen divider will be green during the first 30 seconds and it will be blue for the next 30 seconds. It then becomes gray thereafter.


When you defeat all rounds of the match, 5 cards will automatically be added to your deck. You will also be awarded several upgrade points.

Distribute upgrade points by clicking on the upgrade button next to the desired stat. Stats that you upgrade here are permanent. Some upgrades will cost 2 points instead of the usual 1.

distribute upgrade points

After distributing upgrade points, you will be asked to select 5 additional cards to add to your deck. Click on a card to add it to your deck.

When this is done, you are taken to the opponent selection screen where you can choose your next battle.

If you defeat an opponent you already defeated, the rewards will be reduced (fewer upgrade points and only 2 cards to choose).


Game Over

If your heart reaches 0, you've lost the game. You can then retry the current round by pressing Enter, or press Esc to go back to the opponent selection screen.

You can retry an unlimited number of times, but there are some penalties when you retry:

  • Your extra power will be set to zero.
  • All passives that were in effect will be gone.
  • Score for the current match will be zeroed out.
