So many great things to say about this game, where do I even start? The narrative's the best I've seen so far, the art is unique, beautiful and captivating, and the core concept, while perhaps a bit unpolished, is incredible! The idea of looping around a black hole until you can finally escape it is great, and is improved further by the audiovisual elements around it.
The only harsh criticism I can really give this game is that the movement controls feel quite unresponsive, even if that is the point. I would've liked to have a bit more control over how to avoid enemy ships and their projectiles, since this game is pretty much an on-rails shooter until you get the vertical thrusters and more fuel. Although probably more realistic, I feel like the black hole shouldn't impede your movement decisionmaking this much.
All that said, extremely great work! I would love to see this spun off into a full-fledged game! :)
