Goal: Collect coins, reach the flag at the end, and beat all 100 levels!
Green checkpoint flags save your spot — if a slime hits you after you pass one, you go back to the last checkpoint you touched (the start counts too).
Stuck on a level? Lose 5 times for stomp + high jump (10 sec). Level 3 only: 5 losses = forever invincibility. Non-boss levels: 10 losses = 10 sec invincibility.
Level 50 — floor is lava! There is no safe ground — touch the orange lava and you respawn at your last checkpoint.
Boss levels (every 5th level, except 50): Stomp power lasts forever! Bosses shoot slimes every 7 seconds. Level 100 has 3 bosses!
Blue boxes give stomp power for 10 seconds — jump on top of red slimes to defeat them (+25 pts). Touch them from the side without stomp power and you still lose!
Red boxes let you jump 1.5× higher for 10 seconds.
Jump-through platforms have a light green dashed top — jump up through them from below to land on top.
Controls: Arrow keys or WASD to move. Up, Space, or W to jump. On phones, use the buttons below the game.
Modes: Campaign plays from level 1 onward. Level Select lets you jump to any level (1–100).
