This game upfront has an issue with the weapon selection...on the very first level and beyond.
You start with an MP5 (I think), and whenever you try to select another weapon, and then try to switch BACK, the original weapon is GONE. So, in other words, you’re left with only a PISTOL. All the other guns that you were given in the REDUX version of this game are unavailable. Like, if you want any decent gun at all, do NOT touch the weapon selection button, and you have to deal with using the first weapon given to you (MP5? I forgot). At least this was my experience on my iPhone SE (1st gen 2016) iOS 13/iPod Touch 6G iOS 12.
Beyond that, I suggest 2 enhancements to this game to make the gameplay experience easier on the user (I suggested this earlier on the game “The Sun: Origin):
• Controller/MFi support
• Apple TV support. Make an Apple TV version available to download from the Apple TV store (if you already own the game on iOS/iPadOS, make it ready to download instantly, at no additional cost).
Much thanks for considering these things,
