That intro got me good lol. I had my volume up and it definitely made me jump.
The atmosphere is strong right away. It's got a moody, minimal feel that works really well, and the ambient audio carries a lot of the weight. The little environmental sounds, like walls creaking and water droplets, added a lot as well. The dripping pipe looked great too. Visually it all feels well put together. Dark and abstract. Game hits that Limbo tone.
If you keep building on this and tighten up some of the platforming and puzzle feel, there's definitely something here you could expand into a bigger project. For a first jam jame, this is a strong start.
