Another one I haven't seen mentioned much which was recently shown on TA is
Spectral Souls, which searching impressions of the PSP version, seem to indicate it's a god-awful game due to the incredibly horrendous loading times, for battles, for accessing the menus, even for text boxes to come up in dialogs. Strangely enough, it seems all that loading time is fixed in the iOS port... and seems to play a bit like your normal sRPG, with virtual controls thrown on.
I take it you've tried the usual others? Ravenmark, Legion of the Damned, Call Of Cthulhu The Wasted Land, Hunters 2, Squids 1 & 2, and so on? If not, there's a bunch of good ones that usually make the rounds like that.
