The golden rule of most riddle games: Play fairly.
Seriously, though, don't attempt to cheat with walkthroughs and spoilers unless you want to ruin the fun. It's not satisfying at all.
(Besides, there aren't even any walkthroughs for this game...)
All answers will be in lowercase and without any special character unless specified otherwise.
Like the text above says, the answer isn't obvious. The answer is more than the picture!
If you feel like you may be overthinking it, back up a bit and go over your available clues again.
Certain levels may have 2 or more words,so make sure you type them correctly as is. No other marks/spaces needed.
Look for hints everywhere on the page and try to interpret them.
Certain parts on some levels are interactive, and certain files can also have metadata. Keep that in mind.
Oh, and don't give up. Sure, some levels can be pretty dxmn hard and irritating, but remember, every single one is completely solvable in some way.
This isn't a weekly or a seasonal event, you have unlimited time.
