Not much more than what it is, Tiny Dangerous Dungeons is a bite-sized metroidvania for mobile devices. For those looking such an experience on mobile, this game provides a good scratch of that itch, though lacking in depth and replayability for those wanting a more involved metroidvania on the go.
A cute little game that's worth a bit of your time, as it only requires so little of it to show off all that it has to offer, but what is there is charming enough and leaves a very strong and positive impression.
