Rolling things up in a ball was never more fun!
The game uses cel-shading graphics with a box like 3d models. Really everything is pretty much of cubes or rectangular prisms. Though its doesnt have great realistic graphics like some very serious games, it fits well with the over all weird atmosphere. Everything is also very colorful, which is good.
Theres no voice acting in the game, everything is in text, but theyre are some good sound effects. You hear people screaming when you go towards them and youre big enough to roll them up. Animals squawk when you run into them or roll them up. Also when playing stages, theres always some crazy japanese pop song through out the stages. Some people find it annoying, but i kinda enjoyed it. If you do play it for an excessively long time it may get annoying though.
Theres lots of replay value, trying to get your ball bigger in time limits, but also if you get it big enough in a couple of levels it will lift the time restraints a allow you to make it as big as possible! There is a multiplayer mode but it not that good, usually if some gains a lead there able to knock items of the other player, and usually stay in the lead. Ive played the game for 9:59 minutes, I still like to play it occassionally though.
If your looking for a crazy and weird game to play Katamari Damacy is a good choice.
