Tapa (Islands) by Serkan Yürekli
or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode and the composite Yajilin mode where left click marks cells, right click marks dots in cells or X’s on edges, left click+drag draws lines.)

Nice blend of Tapa and Nurikabe logic in this one. Mind you, I almost forgot that it supposed to follow both sets of logic towards the end of the solve and was treating it more like a Nurikabe than a Tapa with the last clue, which led me miss a basic Tapa deduction for a short while which in turn led me to wonder if there were multiple solutions.
