This game was awesome! The corrupted files are a clever way to fit the theme while still not making the game to easy. It's so cool to return to the old rooms with loads of new gear to absolutely destroy them. Having like 5 guns at the same time is also a cool mechanic which fits the main mechanics very well. If I would have some gripes it would be that it feels a bit unfair to get hit right after leveling up since you cant see what's about to hit you and the players bullets and enemy bullets can be hard to differentiate in the midst of action.
Overall a great entry and one of my favorites so far :)
