P2W, gameplay is just merge+follow a story. You don't get to unlock the story part very often... Unless you pay👎 I've played it for a year or so.

This is the best mobile game I've ever played. The story follows a triangle called "Data Wing" who needs to collect data for an AI program called "Mother." The game features 40 levels, providing approximately 2 hours of gameplay. There are no ads or in-game purchases. The story is amazing and meaningful, so I highly recommend reading the notes and dialogues instead of just playing through the game. The soundtrack is great, and the game is very friendly for speedrunners. Each level includes a feature called Data Uplink, which shows a leaderboard based on your completion time.
