"Obby and the River of Death" is a browser platformer about crossing a dangerous river. The main feature is the swimming mechanic, which changes the controls and physics when you submerge the character in water.

The gameplay is about jumping and swimming from bank to bank while avoiding traps. You control the character using the keyboard to press keys for running, jumping, and paddling. When the character is in water, jumps disappear and smooth paddling begins, which requires fast reactions. Each time you have to decide whether to take the dangerous path on land or risk swimming across the river.

This is for fans of difficult platformers looking for reflex challenges in a browser. It suits those who like earning hard victories without power-ups or easy modes.

Tip: in the first second on the bank, note the river depth because paddling is slower than running, and falling into the water means losing precious time.

How to Play

Control your character to jump, run, and swim through challenging levels. Avoid obstacles and reach the other side of the river.
