Excellent game with really good outside-the-box puzzles and a very unique selling point in the object-perspective-resize mechanic, making it stand out as its own thing rather than being overshadowed by Portal or Antichamber. The story was slightly contrived at times and did feel like it was trying a little too hard compared to the games that obviously influenced it, but its gameplay was extremely strong and the ending sequence was successfully emotional as a climax to the game that was very satisfying to reach and play through, even if the narrative did feel secondary and somewhat tacked-on to what was actually happening in the game.
It is first and foremost a puzzle game and at that it does exceedingly well. The graphics are gorgeous and the sound design is also great; the levels are very well-designed and work perfectly with the various visual tricks it plays on you. Again, the core mechanic of resizing objects with perspective is incredibly strong and well-utilised, and makes Superliminal stand out together with the giants of the genre as a spatial/non-euclidean puzzle game. It's very well-executed and does a fantastic job at conveying the dreamlike atmosphere it's going for. It's fairly short, but it uses the time it has very well and feels like a complete, self-contained journey by the end. A+.
