I purchased this after reading reviews and wasnt disappointed. The graphics are well polished, the difficulties are well varied (Ive been playing on absurd since the start). My lady now steals my phone to play this game to compete with me. The puzzles are dynamic: you move your torch to probe angles and some enemies force you to dodge their projectiles keeping you alert while thinking. Once again, lovely art and colours. Replay value: There are also constantly new puzzles being updated to keep you thinking on the side.
