This is the game, even in demo form, that I liked the most. The atmosphere is excellent, the aesthetics are very pleasant, the hook allows for all kinds of experimentation, and the evolution—ranging from battery management to environments that could go beyond the cold/heat dynamic, such as a sanity system—could enrich it even further.
In my personal taste, this is the game with the most potential to become something bigger and a complete experience.
PS: I touched every grenade without any exception, partly because I didn't see the line, partly because the blast is too good to ignore.
