Thank you for the feedback! You can actually click the green button on the browser to expand it to full screen, although the graphics do become a bit stretched.
The large number of jumpscares were kind of a result of a combination of not enough playtesting outside of me and my teammate and us knowing the puzzles beforehand. The jumpscares occur at the same time as website mutations which also act as hints for the ciphers (unless there are bugs we don't know about), so I think that we kind of made the frequency a bit too often since we didn't have much outside input about the actual cipher difficulty. That is definitely something that we will change if we decide to continue with future updates, or maybe even remove/alter entirely (noise jumpscares/minor glitches only?)
Anyway, glad you enjoyed it!
