Extremely cute! I do wonder why the floor and ceiling is lava for the little kitty though...maybe it's just the anxiety that comes with perceived failure for the little one.
The only thing I can think to make this better, is if you had more freedom with swinging, because there seems to be a pretty broad point of no-return where, no matter what you do, you're screwed.
They don't have to be web-slingin' Spidercats, but to be able to go BACK to collect any missed onigiri, or to reach straight up to help maneuver around a stack of crates. We seem to be affixed to 45 degrees out to the front, and that feels very rigid and constrained considering we're, essentially, web-slinging.
Keep up the great work! I hope the full version is a hit for you!
