Portal (Fixed Edition): A 2D Physics-Based Puzzler with 17 Levels

Experience a faithful 2D adaptation of the Portal universe with this fixed edition by 1ds1ds. Based on lilgreenland's original code, this version polishes the experience across 17 challenging puzzle levels, complete with authentic sound effects ripped directly from Valve's Portal 1 and 2.

Precision Controls & Physics Simulation

Movement is handled with WASD. The portal gun (acquired mid-game) can be aimed with the mouse or the Q/E keys, with mouse-look toggleable via the F key. The game simulates complex interactions: turrets can be picked up (6.01), knocked over with improved physics (5.99), and will even continue firing when off-screen (5.98). Additional keys include P for pause, M for music, R for rain effects, H for physics diagnostics, and L for direct level selection.

Extensive Update History & Easter Eggs

The version history reveals deep polish: new ramp graphics (6.14), map changes (6.08), an easter egg (6.04), and improved bullet physics (5.98). For players seeking the original Flash-based experience, a legacy link (s2online.github.io) is provided. If you enjoy brain-teasing physics games, this 2D puzzler delivers.
