Just finished this game today, it's really good. The concept overall is really fun, and the gameplay does a great job at making you stressed but at the same time requiring full concentration. The glitch effects are all great, and the horror does a great job while only using PNGs. The backdoors and other secrets are also super fun to find, I know you were supposed to get them mainly from another secret, and that fact is true for one of the backdoors, but I had a lot of fun finding the others too. The story is also great, there's a lot of interesting info and details to find, and the ending is simple but effective. I will say again the concentration this game requires of you is super fun, jumping from screen to screen doing everything perfectly is super satisfying, and high score runs are definitely really fun. It's crazy that this amazing game is completely free, would absolutely recommend playing it.
