APT is a puzzle platform game. The game has a first-person view. The project uses FPS mechanics. There is shooting here, but there are no opponents. The emphasis is on the speedy passage of rooms with tests. We control a man in an experimental suit. Above the futuristic armor tests are being carried out in a certain scientific complex. You can see the hands and feet of the protagonist. APT is somewhat reminiscent of Portal in its concept and visual style.
The character has two gadgets with him. Jump Jets gives you the ability to jump high, allowing you to fly into the air for a short period of time. The Tether Shot is an energy cannon built into the suit. Both abilities have a cooldown of a few seconds after being used. The gameplay looks like this. You need to get from the entrance to the exit as quickly as possible. Just running from one point to another on the floor will not work. In the premises there are platforms, analogues of trampolines, exiting ledges, giant buttons, opening doors. Also often come across flying and constantly moving spheres. If you shoot at them, they will pull us towards them with a long beam, thereby accelerating even more. Users can compete among themselves in setting records. For their results, everyone receives certain titles. There is a leaderboard.
