here is the full* hint list
1 use a calculator
2 STOP SHOUTING
3 trace the numbers on a numpad (don't have one? try basic computer coding minus "world")
4 hmm. none of the letters in water are on the bottom row
5 what's the place encircled by roads called?
6 ironic, considering the answer is something that you would flip to use
7 press the keys in order
8 google telephone keypad
9 "look" is a skywalker
10 read it aloud but rephase it, (something like "chemical formula: letters H through O" but not quite)
11 refer to level 7 (this one is hard to give a good hint for)
12 the color what the word looks like (sadly this one doesn't involve hexadecimal color)
13 (this hint is borrowed from unknownIris) "ever see those wifi skits where the pass is "on the fridge" but telling someone that makes them look on the fridge even though its the password.. not hidden. Very literal again" don't forget the ...
14 requires a spread sheet. this one can be a pain, so it's the thing celebrated on valentines day
15 look only at a row column of five pixels
16 the thing you are correcting is in every levei
17 there is a button on the home screen that can load level 0
18 1a 1b 2a 2b, back and forth in continuum
19 i honestly have no clue for this one, i added a region on the map (center of the united states (rounded)), so if you have a hint, click on that and comment it there
20 you would have to kill a cat nine times (without spaces)
21 piano minus pi (another one that's hard to come up with a good hint for).
22 the list of blood types includes, a, o, b, and more
23 try turning the numbers to letters and playing it (or who has a little lamb)
24 1 see 17, 2 "but there's nothing in level -55" and that's intentional
25 This island is famous for its triangle where plains and ships sink often.
26 speaking of sinking ships... also the anime studio that directed the anime was WIT for a few seasons, before it was animated by MAPPA
27 again not sure, maybe something to do with time zones?
28 probably relates to 19 but again i dint know
29 not a color or the word color, but some other thing they have in common (think about the words, not what they represent)
30 i haven't tested this but i assume you give "every number" the level 6 treatment
