Sky Bros — Play Free Online 2 Player Game

Sky Bros sets you and a friend against each other on flying islands. The description says it is suitable for children and offers four game modes.

In Build, you try to put up a house using wood that falls from the sky. Archery has the players shooting arrows at each other on different maps. In Space Ship, you try to knock each other down with spaceships. Woodcutter asks each player to cut 20 trees and carry them to the woodshed.

The controls are not listed in the source, so look at the on-screen instructions in each mode. Having four modes makes it easy to swap if one round gets lopsided. In Woodcutter, planning a route to the woodshed can matter as much as speed.
