"Photon A" has a pretty good layout (which esspecially battle fans will like), but unfortunately there is hardly any eyecandy. Also, it is very small (not to say too small :-) and could get a bit boring after a short time. Besides, Diamondus is not my favourite tileset and overused in average levels.
Somehow i’m unsure if i should recommend a download here. Decide for yourself.
P.S.: The author forgot to set the next level setting. The usual annoying bug when playing on the net…
