D3T are bringing the PSP version of Lemmings to the Vita with added touchscreen controls today on PlayStation Mobile (so you can play it on supporting Androids too).
The iconic 16-bit title has you controlling the suicidal critters with some basic tools to get them to the exit. Best of all, its free on the EU PSN store today (update - paid-for DLC, wondered if there was a catch).
I've dowloaded it for my vita and you get the first 30 levels for free (easy) and for £1.99 you get the other 90 levels (tricky, taxing and mayhem).
The the special levels are 79p which I think is another 90 levels.
So for £2.78 you get a full game that is one of the best and well know puzzle games ever programmed (graphically updated version) and its all touchscreen as well, not to add the visuals look stunning on the ps vita.
This game is a absolute steal !!!!
