Two lanes. Two versions of you. One is solid, one is a ghost. Obstacles barrel toward both, but only the solid one can be hit. Tap to swap which is real. Survive as long as your brain can keep up with two realities at once.<\/strong><\/p>\n

Phase Shift takes the lane-dodge genre and inverts it. Instead of moving left or right to avoid obstacles, you shift between two parallel dimensions — light and dark — deciding which version of yourself is vulnerable at any given moment. It is less about reflexes and more about dual-track awareness, and it will rewire how you process visual information.<\/p>\n

\n

The Two Lanes<\/h2>\n

The screen is split vertically down the middle. The left half is the light lane: a clean, pale background (#F5F5F5<\/code>) with dark gray obstacles. The right half is the dark lane: a deep navy void (#1A1A2E<\/code>) with neon-colored obstacles that glow against the black.<\/p>\n

Your character exists in both lanes simultaneously. In one lane, you are a filled, glowing circle — solid, vulnerable, real. In the other, you are a faint outline — a ghost, intangible, immune. Tap anywhere on the screen to swap which lane holds the solid version of you.<\/p>\n

A pulsing divider line between the lanes shifts between gray and cyan, a constant visual reminder that the boundary between real and unreal is always one tap away.<\/p>\n

\n

Obstacle Behavior<\/h2>\n

Obstacles spawn at the top of the screen and scroll downward toward your character, which is fixed at the 75% mark (three-quarters down the screen). Each obstacle is a rectangle with a random width between 40% and 80% of its lane and a random height between 30 and 80 pixels.<\/p>\n

Every obstacle belongs to one lane. If an obstacle is in the light lane and you are solid in the light lane, it can hit you. If you shift to make the dark lane solid, that same light-lane obstacle passes through your ghost harmlessly.<\/p>\n

Starting at stage 16, the game introduces dual-lane spawns: obstacles appear in both lanes simultaneously, with a 50% chance per spawn cycle. This is the game’s key escalation. With obstacles in both lanes, there is no “safe” lane — you must find the gap between overlapping threats and time your shift to slip through the window where neither lane’s obstacle is at your position.<\/p>\n

\n

Difficulty Progression<\/h2>\n

Phase Shift uses a stage system where each stage lasts exactly 5 seconds. The game tracks three escalating parameters:<\/p>\n

Speed<\/h3>\n\n\n\n\n\n\n\n\n\n
Stage<\/th>\nScroll Speed (px\/s)<\/th>\nFeel<\/th>\n<\/tr>\n<\/thead>\n
1<\/td>\n300<\/td>\nLeisurely<\/td>\n<\/tr>\n
10<\/td>\n390<\/td>\nBrisk<\/td>\n<\/tr>\n
20<\/td>\n490<\/td>\nFast<\/td>\n<\/tr>\n
30<\/td>\n590<\/td>\nFrantic<\/td>\n<\/tr>\n
50+<\/td>\n790 (near cap)<\/td>\nExtreme<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Speed is capped at 800 px\/s. The formula is 300 + (stage - 1) * 10<\/code>, climbing 10 px\/s per stage.<\/p>\n

Spawn Interval<\/h3>\n\n\n\n\n\n\n\n\n
Stage<\/th>\nSpawn Interval (s)<\/th>\nObstacles per Second<\/th>\n<\/tr>\n<\/thead>\n
1<\/td>\n0.90<\/td>\n~1.1<\/td>\n<\/tr>\n
10<\/td>\n0.63<\/td>\n~1.6<\/td>\n<\/tr>\n
20<\/td>\n0.33<\/td>\n~3.0<\/td>\n<\/tr>\n
21+<\/td>\n0.30 (floor)<\/td>\n~3.3<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The spawn interval decreases by 0.03 seconds per stage, flooring at 0.3 seconds. Combined with dual-lane spawns starting at stage 16, the screen fills rapidly in the late game.<\/p>\n

Dual-Lane Spawns (Stage 16+)<\/h3>\n

Before stage 16, every spawn puts an obstacle in one lane only. After stage 16, each spawn has a 50% chance of placing obstacles in both lanes. This fundamentally changes the game from “which lane is safe?” to “when is the gap between obstacles in both lanes?”<\/p>\n

\n

Collision Detection<\/h2>\n

The collision system checks only obstacles in the lane where you are currently solid. For each obstacle, it performs a two-axis overlap test:<\/p>\n
