Wow, what a game!
Fantastic work. Very atmospheric and beautiful. The visual style and feel was great.
Extremely challenging gameplay, but addictive. You make a mistake and you just want to try again and again until you get it.
Only criticism is perhaps it might have been nice to have some music. Something subtle I think – although, I'm not too sure, because visually I think it calls for a relaxing and subtle tune, but the gameplay is more tense and frustrating than that, so perhaps they'd be at odds. I'd be interested to hear it with music and see how it affects the mood. As I think about it, it's not even a criticism, it's more of a "I wonder if?"
Congrats on the great entry.
