Welcome to Zenith Clicker, where the goal is to select required Tarot cards and send players to scale the tower.  
As you keep climbing, more tricky players will come!  
Leaderboards aren't available, but how high can you reach?

Almost all art and sounds are from TETR.IO, a modern yet familiar online stacker game by osk with amazing graphics and music.

WARNING: This game requires the knowledge of the mechanics and mods of TETR.IO's Quick Play 2, or you won't get much fun.
If you like the Quick Play 2 mode but don't know much about it, check another repo of mine: QP2 Documentation (in Chinese, with some translated forks). It's nearly a full explanation of QP2, including many technical details behind the scenes, which can allow you to play QP2 with better strats!

Zenith Clicker is a game inspired by the Quick Play 2 mod selection menu of TETR.IO. Its interactive feel is really not good for quickly picking the mods needed, and there's still no convenient way to know which mods are included in a specific combo.

After you start the game, you will see three mod combinations, which are called "quests", shown at the top of the screen. Select the mods which are contained by the first (largest) one, then press the Start button to commit.

Pass quests with one click at most on each card to get "perfect pass", which gives extra attack and increases B2B. At B2Bx4, it starts charging up a huge Surge Attack that releases all at once at the end of your chain.

Each mod creates a unique experience by twisting the rules, but also increases the difficulty.

• Cards are 10px (9%) closer together.
• Climb speed decays 67% faster.
• Cards are deactivated after failure.
• All actions happen on button release instead of button press.
• AS keyboard hints are not shown (if enabled).

• You cannot manually deselect cards.

• Cards are lightly shuffled at the start of floors 1, 2, 5, and 8. The cards will always be in or adjacent to their correct position.

• Automatically commit some time after the first card flip. The timer starts at 9s at floor 1, and decreases every floor until 4s at floor 10. The timer will also automatically start if you flip no cards for 2.6s.

• Cards are 20px (18%) further apart.
• Cards must be pressed twice to activate, but deactivating still takes a single press.

• Quests are harder.
• Quests can sometimes be slightly shuffled.
• TODO: add specifics to difficulty change

• All cards are face down.
• Quest colours are desaturated.
• Quest hints are only shown for a moment every two seconds..

• You can flip cards with your keyboard: on ANSI QWERTY layout, the inputs are 1-9, Q-O, or A-L. If cards are shuffled by (r)MS, they are flipped based on their position, not by which card they are.
• The RESET button is replaced with SPIN. Using SPIN quickly flips all cards one-by-one.
• Flipping a card will apply a burn to it, indicated by it flashing yellow. Burns last 3s and this duration increases by 0.5s per floor. They can be removed by committing (even if the selected card is a wrong one) or pressing SPIN. Flipping a burned card will cause you to get wounded, force-flipping two cards. These cards do not get a Burn.

• There are two "players" instead of one. You can swap players by activating the Duo card, or by completing the second quest in the queue (the cards will be highlighted pink while you do this).
• If one player is incapacitated, your ascension is halved and quests becomes harder, but they can be revived by completing some revive prompts.
• Quests are a bit harder.
• TODO: specifics on tasks

Main idea: Sending attacks to knock out your opponent and sending mod effects to disturb them

Sending Attack: Now your attacks will deal damage directly to the opponent's HP after some time, but the opponent is also able to cancel them.

Sending Mod: Breaking surge will apply mod(s) on your opponent for some time.

The game ends when a player's HP reaches zero.

Main idea: Sending mod effect to an opponent

Two players start the run, using most of the same gameplay as in single player.

Sending Buffer: Your attack power is converted into a corresponding duration of "time" (1 attack = 1 second) and stored in this buffer.
When the buffer remains inactive (no increase) for 3 seconds or you take time-based damage, the stored time will be sent to the opponent. The last card you activated is the effect you will send.

Cancelling: Before sending effect-time to the opponent, it will try to cancel the same effect currently active on you, with a 2x multiplier.
For example, it's not possible to force EX on the opponent if you already have EX.

Sending: After cancelling, any excess time in the sending buffer is sent to the opponent.

The game ends when a player's HP reaches zero.
