I tried this earlier on my DS (via an R4 Revolution & also CycloDS - worked fine on both).
It's a nice polished little game and evokes the feel of Super Foul Egg very well. Everything is smooth and responds quickly.
It may just be me being rubbish, but I played on level 0 difficulty and starting height and really struggled to beat the AI opponent!
Also, some in-game music might be nice?
