Katamari Damacy-Kun (塊魂くん lit, Katamari Damashii-Kun) is a Japanese-only mobile phone game that was distributed on i-mode, Yahoo! Kentai, and EZweb. It's a 2D Katamari game based on the ending 8-bit minigame from Me & My Katamari. Along with including the original levels from M&MK, it has many unique stages as well. Also included is a story (much like the one the original Katamari Damacy had) and a Collection, where you can look at rolled up items. This has a few new modes, including a tutorial and the Story Mode. Apparently, something of interest happens after completing the collection.
