Time Warper

A 2D arcade shooter where you can stop time and scrub the world backwards — but never yourself.

Play it: https://andreasgraykristoffersen.github.io/time-warper/

The idea

Press E and time stops. Scroll backwards as far as you like: the swarm, the bullets and the damage you dealt all unwind with it — but you stay standing exactly where you are, and so do your hearts, your xp and every upgrade you own. Rewinding is unlimited, but every fifth rewind costs you a heart.

Modes

Mode	How it works
Survive	Two minutes. Splinter lands at 1:30 left, Fracture at 1:00, Terminus at 0:30 — they stay. Outlive the clock.
Endless	No deadline, a stopwatch counting up. A boss every 30 seconds, each cycle harder than the last. Death is the only ending.
Boss duels	Each boss freezes the clock dead at 30 and gives you thirty seconds to kill it. Win and the clock restarts; that boss never returns. Killing all three is the only way to win.

Controls

• WASD / arrows move, mouse aims — the gun fires on its own
• E stop time, wheel / drag / A·D to scrub, E or Space to land
• 1 2 3 pick an upgrade · F fullscreen · M mute
• On touch: drag the left half to move, the right half to aim

Upgrades

Kills are xp. Every level freezes time and offers three of fifty upgrades — lasers, bomblets, ring volleys, orbit blades, medic rounds that drop healing on the ground, and Echo, which leaves a copy of you replaying the seconds you just erased, carrying your whole arsenal. Some upgrades only appear once you own what they build on.
