Next up is Mekorama, a game that millions will likely love. It's an atmospherical puzzle game that's very calm, casual, and minimal, but in a good way. It's similar in style to Monument Valley, but it's completely free.
Basically, you're working on a word or level one at a time, where you can change the angle and move the level around until you make your way to the end of the puzzle. You'll enjoy some nice calm music, increasing difficulty, and 50 puzzling mechanical dioramas.
Help your little robot friend reach the end of each puzzle, and have fun. It has relaxing gameplay, collectible level cards, and charming robots.
Here's the deal. It's completely free, and the "in-app purchase" is optional. There are NO ads and no in-app purchase limits. Basically, if you really enjoy the game you can donate to the developer. As much or as little as you'd like. The choice is yours.
