NOTE FOR PEOPLE WITH EPILEPSY OR SIMILAR: There is a bugged state where the screen shakes and objects duplicate wildly. Be aware if those things cause problems for you.
The "losing moves" as you take damage/shoot grenades is really clever. I just wish there were more keys to pick up. I got into a very unfortunate situation a couple of times where I didn't have grenades and there weren't any keys I could find, making me pretty much out of luck.
As I mentioned in the note, there was the bugged state where all of a sudden I would have no keys and the screen would start going mental, duplicating objects and shaking like crazy. A quick refresh fixed it, so not a huge deal but I wanted to be sure to leave a note for those kind of things
