Really cute. It feels like you focused on the core of what you wanted to do quite well, and therefore it feels more complete (if that makes sense).
While I’d seen the idea before (Lovers in a Dangerous Spacetime for example – recommended game if you didn’t get the idea from there b.t.w.), the addition of hazards within the ‘smaller’ space is new, and a welcome twist – though it does make it right difficult at times.
(The description wasn’t quite clear if the art was made for and during the jam, or just by this artist, but I’m going to assume good faith here and handle it as if it is.)
