Can I change the controls?

Does the game need sound?

Not strictly, but audio cues often signal incoming attacks, so playing with sound on makes a noticeable difference in harder stages.

What it's like to play

Fast hands help, but pattern recognition wins. An action game shows you an enemy, lets you get hit once, and expects you to learn from it. Over a session you build a library of tells: this one lunges, that one shoots on a count of three. Stages are short, health is precious, and the boss at the end of a section is where everything you learned gets tested.

How to play

1Learn to move and attack on the first screen, then deliberately watch the first enemy attack once before fighting back.
2Dodge toward open space, never toward a wall, and keep your back clear of other enemies.
3Alternate attacking with short retreats. Constant offence drains your health faster than anything else.
4Before a boss, collect every pickup on the stage. You will need the margin.

Why it's worth a go

Shark io delivers a proper fight with no setup. It is free, runs in the browser, and needs no download or account. Stages are tight and sessions are short enough to play in a break, long enough to feel like you did something.

Who it's for

Suits players with decent reflexes and a taste for pressure. Teenagers and adults are the natural fit, with older children managing the early stages. Younger players will likely find it too fast.
