Probably the most atmospheric, intriguing game I've played here in a while. The art makes for such disturbing, yet sympathetic creatures of the saps, with so little resolution. A pleasing color pallete, minimalism at its finest, even the lack of 'normal' music helps with the ambiance. Even the mechanics highlight our protagonist's helplessness- no legs to jump, or hands to claw.
The story was an interesting metaphor, and innovative at that. It reads like a grim warning, and even if it's short there's still time for to set up very telling tidbits. From "I never liked that one anyways." and "You were always my favorite." to the simple fact that the hive completely drops its swearing in the ending.
The NPCs fit perfectly. I rather liked the intro! The dialogue there is great and valuable, and rather than skipping it, I think the best thing to do would be speeding up the section that scrolls through the hive, as it's the actually monotonous part.
(While it does set some ambiance, it could use a bit more movement than just the walls slowly scrolling. It'd be nice to see a rusted pipe fall loose into the hive, knocking out our sap and beginning the story. Or just have some sap faces moan when the credits show.)
i'd love more of this, maybe multiple endings, even if none of them were that hopeful. Still, I guess that would cheapen the game for you, so I guess that's that.
