Found this beta recently and still having a good time with it.
Cartoon/comic book style graphics.
The game has a cash shop but the CS items are not as good as the crafted/collector items. So the item grinding is not so meaningless. The in game shop does not have that many items yet.
You can decorate your lobby with vanity furniture which can be bought or crafted.
Nearly all items are temporary. Ranging from 5 days - 30 days. So even though top players have advantages they are only temporary.
The gameplay has many extra nuances on top of the jumping. There are advanced timing techniques to help you win.
I usually play the Item Mode - reminiscent of Mario Kart.
Gameplay can be considered repetitive but racing games have that attatched to them don't they? XD
