Geometri Tag Wars

Geometri Tag Wars is a tag game for two where the flag is bad news. Whoever has the flag loses, so you need to pass it to your friend before the time runs out. The one who gets rid of it in time wins the match.

You can also collect emeralds along the way, which let you buy different costumes. The source doesn't list the controls, so the instructions shown at the start explain what each player does.

It suits friends who like quick, simple rounds. A tip is to keep an eye on the timer and aim to pass the flag with a few seconds to spare, not at the last moment. There is also Geometri Tag Wars 2 Players if you want the related version.
