Cupling is such a fun and creative concept for a game—I really love what I’ve seen so far! It actually reminds me a bit of Bean’s Quest and Bean Dreams, those minimalist platformers on mobile, which is a great vibe to channel.
One small thing I noticed (playing on mobile, so I’m not sure if it’s the same on desktop) is that some of the parallax background elements dip below the floor in the first stage. The water foreground in particular feels a little lower here than it does in later levels, where it obscures the stage more consistently or where the floor extends down further to cover it.
That said, the potential here is huge—I’m really excited to see where you take this project!
