Unbound: Worlds Apart is a fantastic, extremely well made and extremely challenging (for me at least) 2D puzzle platformer in which you guide a mage called Soli through a maze of puzzles using different types of portals and abilities.
The graphics are great, the soundtrack is great, but it did cost me some nerves as some of the challenges were annoyingly hard and here and there it needed the support of the next generation.

All in all, a wonderful game with great gameplay that’s a lot of fun to play (despite the difficulties I had). Definitely a recommendation, especially if you like games like Ori.
