I’m not sure how long the game is free for, but I received it for free after hearing about it on reddit, I believe discounted from the full price of $2.99 or less.
Now the game isn’t very long, I played for 4 sessions, maybe an hour, hour and a half total. It is enjoyable, and you’ll unlock an endless mode and run for high scores.
The graphics are inspired by the 80s, all sorts of bright neons against a black background. All of the gameplay comes through 1-2 second long Warioware style mini-games, and you’ll be doing several of them at a time. The game is heart pounding and fast-paced, and I enjoyed my time with it but it does feel a little short at the end of the day.
That said, it was a free download with no in-app purchases that I was happy to play. Looking forward to their next project.
