I found this game to be monumentally disappointing. SuperBunnyHop's review covers most of the reasons why I feel this way:
Yeah that review says it pretty well. Owlboy is obviously a labour of love with great visuals and soundtrack, but it fell short in the gameplay. In both the exploration and dungeon parts I found myself going through the motions pretty quickly, there was nothing that really stood out in terms of design. Playing through this was such a disappointing experience because most elements were there for a great game, but it fell short where it really mattered.
