Love this game! Quite a classic. It's a little short, but Portal 2 more than makes up for it. Always remember, the cake is a lie.

Отличная игра-головоломка-экшен, одна из моих самых любимых.

you can place a portal on the toilet at the first room then one on ur bum so when you poo it falls infinitely. its very fun to do but if you leave it too long game theory says it will make a black hole.

classic game

very interesting addition to the half life universe
