The new PC/Switch version also adds a few more subtle features to what is otherwise the same game as the PS3 version we reviewed those years ago. The first, and perhaps simplest, is that the game now renders at 1080p rather than 720p. Its a notable improvement, though why it doesnt support 4K (or even better, simply scale to your screen resolution) is a mystery. Also, they made Infinite mode easier by offering the player the choice to press a button to automatically and instantly max out their power-ups. Given how difficult the game is, and how certain bosses are quite difficult to hit without some power-ups, it can help quite a lot. They also added fast-forward and rewind buttons. Finally, you can choose whether or not your co-op partner can be damaged by you in two-player mode or not.
