I agree about SPD. While it's great for a mobile game and looks gorgeous, I find the gameplay somewhat shallow for a roguelike.

If I have a monitor and keyboard at hand, I prefer to play the likes of ADOM (classic version, not Ultimate), Brogue, Legerdemain, Sil, DCSS, etc. which offer more depth, strategic complexity and meaningful choices, IMHO.

Haven't tried the frog one, will do at some point.
