Seems absolutely pointless for a match-3 to me? All it does is makes the graphics REALLY pixel-y on a lower-end phone, which isn’t a good impression for something that SHOULD be able to run on a low-end phone with no issues (aka: it’s a puzzle game, it should only be 2D?)
Maybe this is due to the PC release coming, but even then nobody had issues with 2D graphics for characters/enemies in Puzzle Quest 1/CotW and Puzzle Quest 2.
People had issues with Puzzle Quest 2’s game design, which has nothing to do with graphics.
