My first puzzle! (Very Hard)

Hello 👋
I haven't actually made any puzzles on here before so this is kinda exciting :3
This puzzle has multiple levels to it, and I made it sorta themed on steam for the first two but then I got bored of the theme thing lol. The last level will probably be very difficult without a hint, but I'll see how people go. The game is NodeBuster https://store.steampowered.com/app/3107330/Nodebuster/
Here's the link to the first level https://2solve.me/quiz/40a29827/level-1-steam-scavenger-hunt
I know chrome gives you a warning about the site, but you can trust it, it's been used several times before on sg.
Anyway, have fun!
EDIT: I know a lot of people are struggling with level 4, which I kind of expected. Look closer at my profile on the "part you weren't expecting".
P.S. The giveaway ends on my birthday, April 23
EDIT: I am so sorry, the solution was meant to be hidden in my profile picture, but it got too heavily compressed. I am working on a fix right now. Again, I am so sorry.
EDIT: The puzzle is now fixed, I have changed where the solution is. Thank you for understanding.
