Islets is a nice little self contained metroidvania. Made by a single guy, it's very well polished, no bugs, good gameplay loop and really nothing major to complain about. The game consists of 5 islands, which you need to bring back together by defeating bosses. Stitching islands together opens more paths, along with various movement and combat abilities such as double jump and being able to create platforms with your arrows. I only got stuck on where to go a couple of times. If anything, my only complaint was that it was too easy; I never really had to think or retry bosses more than a couple of times. If you're a fan of the genre, it's worth playing. Completed in 7 hours.
