Must Have For Any Portal Fan

This game is absolutely incredible. All of the mechanics are amazingly true to Portal—including cubes and buttons, unstationary scaffolds, high energy pellets, and sentry turrets! The music sounds strikingly similar to the music played in the Old Aperture areas of Portal 2 (i.e. “You Are Not Part of the Control Group”). Another great feature is the level editor, and the ability to share your test chambers with other players, similar to Portal 2’s Perpetual Testing Initiative. The game’s controls are also very easy to learn. The only thing that this game lacks is mechanics from Portal 2 (lasers, hard light bridges, mobility gels, aerial faith plates, etc). I would love to see some of the Portal 2 elements implemented into this app in future updates! As a whole, this game manages to perfectly capture the spirit of Portal (besides the absence of GLaDOS). If you’re a Portal fan, you should definitely download TwoTime Portal. And no, I was not paid to write this. Seriously.

Amazing, But could be improved

I am a very big fan of Valve’s Portal series, so when I saw that this game kept true to that, I decided to give it a go, and I was not disappointed!

The gameplay is simple yet fun, but I’d like it if you could make it to where when the phone is tilted on its side, the game would adjust itself to match.

The mechanics in the game are surprisingly true to Portal even though this isn’t an official portal game. I would like to see some mechanics added that resemble that of Portal’s, such as jumper plates, lasers along with mirror cubes and activators that only turn on when hit with a laser, and missile turrets. I also would like if the cardboard boxes can be replaced with weighted storage cubes because the cardboard boxes don’t make much sense with the game you are trying to imitate.

One thing that I am not fond of is the fact that you can get damaged and have to pay in-game currency to fix it, otherwise you can’t play any levels. The battery system is a good touch and the batteries don’t take too long charging, either.

It’s overall a fantastic and well made game that I would recommended to any Portal fan.

Please add more levels soon!

This game is fun! I just wish it went on longer, also, can you add a level editor possibly and an option to change how many recursive portals there can be? Perfect game I just wish for more levels!
