It really is a 'game game' - primarily concerned with its gameplay and it shows. The progression feels even more fluid than in the original and makes you want to complete it. Puzzles, movement and interactions are great and it encourages to try things out, and often enough they work. The only issue I see is endgame rewards, where you killed all enemies, won't encounter anymore, and then get a damage upgrade and walk around with 30 health that you'll never ever lose
