As both a publisher and developer, CIRCLE Entertainment is among the most prolific content creators on the 3DS eShop, and it has yet another title to show off; it looks rather promising, too.
It's a futuristic fast-paced runner (developed by Flyhigh Works) with the emphasis evidently on difficulty. The only player controls are jump and 'change', as you need to switch between two colours to match hazards and attacks. You can get a look at it in the trailer below.
It's coming out on 15th September in North America and 22nd September in Europe, priced at $5 / €5, so it's not far away.
