水晶球 Crystal Ball

Game guide, controls & how to play · 遊戲說明、操作與玩法

About the game · 遊戲簡介

Crystal Ball is a browser-based action game (HTML5 canvas). You control a small dragon on a platform stage. Enemies drop in, move on platforms, and shoot at you. You fight back with seven different “crystal ball” shots — each key is a different element or effect, with its own ammo pool that reloads slowly over time. Clear the stage to reach the next of 20 levels; layouts, enemy counts, and difficulty patterns change every stage.

Score: +200 per enemy KO, plus a level-clear bonus. HUD shows score, HP, lives, level, and ammo.
Skills: Jump on your own shots to ride them, melt ice platforms with fire, cool dangerous hot floors with water shots, and chain slows, burns, and poison on enemies.

《水晶球》是網頁上的橫版動作小遊戲（HTML5 畫布）。你操作一隻小龍在平台場地戰鬥，敵人會落下、在平台上移動並朝你發射子彈。你用七種不同的水晶球發射還擊——每個按鍵一種效果，各有彈藥上限，用掉後會隨時間慢慢回復（裝填偏慢，須省著用）。清空敵人即可進入下一關，共 20 關，每關地形與敵人組合不同。

分數：擊殺敵人 +200，通關另有獎勵。畫面上方可見分數、HP、生命、關卡與各彈種彈藥。
技巧：可跳上自己的發射物頂端搭乘移動；火可融冰台，水屬發射可冷卻燙人的熱台；緩速、燃燒、中毒等可疊加運用。

Keyboard controls · 鍵盤操作

Focus the game canvas (click it) so keys register. Holding multiple shot keys only registers the first in this order: Z → X → … → M.

← → — Move left / right.
Space or ↑ — Jump. Works on the ground, on a rising shot, or with feet on a shot’s top surface.
Enter — After Game Over, press Enter to retry the current level with 5 lives and full HP.

HUD (top of canvas): HP · current/max · Lives · Restart button · Level · Shots line — each letter shows ammo; a dot · means that shot type is still on fire cooldown before you can shoot again.

Seven shots (each costs 1 ammo; ammo regenerates after a delay)

Key	Effect on enemies	Platforms
`Z`	Ice — stops horizontal movement for a short time	Water-type: cools hot platforms
`X`	Fire — hit damage + burn (HP drains over time)	Fire: melts ice platforms
`C`	Water stream — strong slow	Water-type: cools hot platforms
`V`	Root — brief full stop (no movement)	—
`B`	Shrink — smaller hitbox for a few seconds	—
`N`	Poison — slow HP drain over time	—
`M`	Heavy — −3 enemy HP in one hit	—

Click the canvas or press any key once if there is no sound (browser autoplay).

請先點一下遊戲畫布讓鍵盤操作作用。若同時按住多個發射鍵，只會依序優先：Z → X → … → M。

← → — 左右移動。
空白鍵 或 ↑ — 跳躍（地面、站在上升發射物上、或腳踩在發射物頂皆可）。
Enter — 遊戲結束後按 Enter，以 5 條命與滿 HP重打本關。

畫面上方 HUD： HP 現值／上限 · 生命 · 重新開始 · 關卡 · Shots 彈藥 一行——英文字母旁為剩餘彈數；顯示 · 表示該彈種尚在射擊冷卻中。

七種發射（各耗 1 彈藥；彈藥會延遲回復）

按鍵	對敵效果	平台
`Z`	冰凍——短時間無法橫向移動	水屬：冷卻熱台
`X`	火焰——瞬傷 + 燃燒持續扣血	火：融化冰台
`C`	水彈——強力緩速	水屬：冷卻熱台
`V`	定身——短暫完全無法移動	—
`B`	縮小——判定變小一段時間	—
`N`	毒——緩慢持續扣血	—
`M`	重擊——單發扣敵方 3 HP	—

How to play · 玩法詳解

Goal: Defeat every enemy on the stage. A short “level clear” overlay appears; after about one second the next level loads.
Levels: 20 stages, then loop to level 1. Each level changes enemy count, max HP, and speed using different patterns (swarms, tanks, rush waves, mixed squads, etc.).
Your HP & lives: You have an HP bar above the dragon and up to 5 lives. Damage sources: enemy bullet ≈ −1 HP, touching an enemy ≈ −2 HP, standing on a hot platform (until cooled) ticks damage. When HP reaches 0, you lose one life, respawn on the main floating pad with full HP, and get longer invulnerability. Clearing a level does not refill HP or lives — your current values carry to the next stage. Only Restart (HUD) or Game Over → Enter resets to 5 lives and full HP.
Restart: Reloads the current level and resets lives + HP + ammo to defaults.
Enemy combat: Each enemy has HP (bar above them). They shoot toward you on a timer (generally faster on higher levels and on tougher enemies). Your shots cost 1 ammo each, apply that type’s instant damage (usually 1; M = 3) and status effects. +200 score per KO.
Ammo: Each of the seven keys has its own magazine and slow regeneration between shots — plan bursts and use the HUD.
Stage layout: Mid-level platforms plus floating pads at the bottom (no continuous floor). Element platforms: some stages have slippery ice — X melts it. Some have hot tiles — Z or C cools them.
Your shots & ceiling: Shots float upward and bounce off walls; they pop at the top of the screen. You can stomp them or bump from below to clear them.
Riding shots: Land on top of a shot to ride it. Near the top of the screen you are pushed back down so the dragon stays visible.
Last enemy: When only one enemy remains, it moves faster (“angry”), including its shots.
Character panel: Right of the game (below on narrow screens) — pick Bub, Bob, Rose, etc. (cosmetic only).

目標： 清空場上所有敵人。出現通關提示後約 1 秒自動進入下一關。
關卡： 共 20 關，全破後從第 1 關再玩。每關敵人數量、血量、移速依關卡類型變化（人海、坦克、快攻、混合編隊等）。
你的 HP 與生命： 頭上有 HP 條，最多 5 條命。受傷來源：敵方子彈約 扣 1 HP，身體碰敵人約 扣 2 HP，踩在未冷卻的熱台上會持續受傷。HP 歸零扣一命，在地板滿 HP 重生並有較長無敵。過關不會補滿 HP 與命數，會保留到下一關。只有按重新開始或遊戲結束後 Enter才會回到 5 命與滿 HP。
重新開始： 重載目前關卡，生命、HP、彈藥恢復為預設。
敵方戰鬥： 敵人有 HP 條，會定時朝你射擊（後期與強敵通常更密）。你的射擊每次耗 1 彈藥，造成該彈的瞬間傷害（多為 1，M 為 3）並附帶狀態。擊殺 +200 分。
彈藥： 七種發射各有彈倉，用掉後需等待回復（裝填偏慢），請看 HUD 規劃火力。
場地： 中層平台 + 底部浮空小平台（無整片地板）。屬性：冰台可用 X 融；熱台可用 Z／C 冷卻。
發射物與頂部： 發射物上飄並左右反彈，撞上緣會消失；也可踩踏或由下往上頂破。
搭乘： 可站在上升中的發射物頂上移動；靠近畫面上方會被擠回可視區。
最後一人： 只剩一名敵人時會變快（憤怒），含子彈壓力。
角色面板： 畫布右側（窄螢幕在下方）切換外觀，不影響能力。

Quick tips · 小提示

Conserve ammo: regen is slow — open with control effects (Z C V) then burst damage (M) on big targets.
Enemy bullets are tinted like their shooter; dodge or use brief invulnerability after a hit to read patterns.
Pop your own shots with a stomp or bump from below if they block jumps; riding them saves time crossing gaps.
Level clear adds bonus score (scales with stage number).
There is no solid ground under the arena — only floating pads and mid-level platforms. Fall too far and you respawn on the main pad.

彈藥回復偏慢，可先用手控彈（Z C V）再對厚血敵用 M 重擊。
敵彈顏色大致對應發射者；受擊後短暫無敵可趁機重整走位。
自己的發射物若擋路可踩踏或由下頂破；必要時跳上去當移動平台。
通關有額外分數（隨關卡加碼）。
場地下方沒有整片地板，僅有浮空小平台與中層平台；落得太低會送回中央主平台。
