RayForce/Layer Section/Gunlock has been reviewed elsewhere. This is an amazing game.
The iOS port is graphically very solid, I have no problems on an iPad Air 2 and didnt think it was blurry or anything.
This is a game whose difficulty grade changes a lot with touch. I can generally 1cc through to the second level final boss on the Saturn version of this game, but I no missed the whole second level (including the scary boss) first try on iOS. This is in Remix mode.
Arcade mode, as other reviews have noted, feels wrong, even though it tries to emulate the original difficulty level by slowing the ship down. Maybe with practice this would be okay, but at this moment I would just go back and play on a console to get the spot on difficulty.
For under $10 this is a snap purchase for me. Kudos to Taito for bringing their back catalog to iOS.
