This game's graphics are really good for its low resolution. Every scene is colourful and object distinct without appearing cartoonish. Secrets are subtle enough to blend in at first glance but don't require a pixel hunt to locate (and often come with contextual clues). Plus there's the visible day-night cycle that ties into several puzzles. The atmosphere and readability is seriously better than a lot of paid point and click games.
I haven't finished Spectacle yet so I can't comment as strongly on the puzzles; so far they're good. I'm just happy to find another polished adventure game that's focused on exploration and intuitive puzzles rather than NPC dialogue and pipe mazes or whatever. Thank you, devs, for your work.
Minor gripe: Please allow text writing to be sped up or automatically skipped in your next project. Double clicking everything to read at a comfortable pace is a nuisance.
