This is a really good one. This might be because we're in a discord together, but I feel like a polished/expanded version of this (per the note below I'm thinking of the feeling of "bigness", not necessarily the size of individual rooms) belongs in at least a $5 Steam tier. As I mentioned on stream, not a marketer tho, and the genre is a mashup of sorts. I'd just be hoping it hit the right streamer(s).
Enjoyment/Execution 4/5 each. Some of the precisiony platforming stuff was a bit for me, and I sometimes had trouble judging distances between platforms. However, the vibes of the thing made it quite enjoyable. I would consider giving the player a little less to traverse--not a LOT less, but maybe 2/3 less.
Sensory 5/5. Despite lack of proper jump it almost feels like you got at some of the aesthetic reasons I've played so much N++. Might be a bias but it just tickled my brain in the right ways.
Metroidvania 5/5. Unique abilities that change your traversal through a level, and only one of them is kind of a jump.
Relevance to theme: 5/5. Everything feels very stark and maybe even 'brutalist.' And you set out what you wanted to do per your interpretation, good show.
