Welcome to 3keys game reviews

portal is a puzzle that was made by valve in the source engine in 2007. It came in the orange box along with half life 2 and its episodes and team fortress 2

this is my personal opion on portal

pros

• made in source
• unique style
• satifying movment
• good puzzles

cons

• can make some people motion sick
• (old) there can be some visual glitches
• (old portal) some of the geometry can look off

overall, portal is very fun. the puzzles offer a challenge and (if you played the xbox 360 version of the game like me) the challenge maps were fun. i loved the lab aesthetic of the game and i hope to add it to my game some day. 9/10 a true valve classic
