I finally got back to We Love Katamari tonight and completed a handful more stages. Fortunately most of them at least had a slight thematic twist to them, even if it boiled down to the same old get-big-enough-within-the-time-limit.
The sumo and zoo levels only count certain types of items towards your total, but there’s plenty of them around. The gingerbread house level was more of a diversion than a real challenge, since everything’s right in one spot. The firefly level was really just a test of how efficiently you can cover areas, since there’s no size differences. And finally, I’m not even sure what the goal of the snow level was, since there’s no timer or size goal at all, so maybe it was just another diversion.
It shouldn’t take too much longer to finish it off, since it’s a fairly short game.
