Chinese! Let's compare the simplest chinese hieroglyphs to alphabetic signs we know:
E & M use 4 strokes, so let's watch chinese hieroglyphs of up to 4 strokes thinking of them as of simple enough to make letters, and I take japanese form of it, also to compare it with chinese hieroglyphs:

If they're so simple I will be able to recognize them without a dictionary, so I think,

一 is one
乙 is 2nd  (all the other one-stroke symbols are not used as separated hieroglyphs)

二 is two
人 is man  (⺅is its abbreviated form - it's always on the left of hieroglyph (there's no space before is))
入 is enter
八 is eight
刀 is katana
力 is force
勹 is wrapping, but I didn't recognize it, I thought it's taking
十 is ten
卜 looks like runic ᚿ and what do you think it stands for in japanese? (suddenly I realized that I looked japanese radicals in chinese dictionary. by accident.
 卜 is divining, telling a fortune, predicting, choosing, fixing. I don't know what kind of fixing it stands for, but other ones tell of what runes were used for in Germania of Tacitus. It is not recognizable hieroglyph though, I wasn't sure of its meaning.
九 is nine, but I didn't recognize it.

口 is mouth, but for some reason I forgot it. Probably bugged by 囚
土 is soil
士 is samurai, but I didn't remember it
大 is big
女 is woman (notice, that woman is 3 strokes & man only 2 - but it looks like it could be of 4 strokes, or it looks like it could be of 5 points a venus star)
子 is child
小 is small
山 is mountain
川 is river
巛 is curving river, but I didn't know it of course.
工 is worker but I didn't know it.
干 is dried but I didn't know it
彡 three, hair ornament, short hair or fur radical (words in grey are new to me)
彳 stop, linger, loiter, going man radical
I began to collecting some unrelated signs, I lost my way, but back on track

心 is heart, everybody knows it
手 is hand (I knew it but forgot together with mouth) it looks like E
日 day, sun, Japan, counter for days
曰 say, reason, pretext, history, past, flat sun radical (no. 73)
月 month, moon
木 is tree
止 stop, halt (I thought it was stand as in stand up)
毛 is hair
气 spirit, steam radical (no. 84)
水 is water
火 is fire (funny that these three stand together. soil was before)
there's a funny hieroglyph combining 火 & 水: 爆 bomb, burst open, pop, split
so here I run a little forward in that table and give another hieroglyph to making this complex one I know of:
井 is well (well, well crib, town, community)
勿 not, must not, do not, be not (I thought it was an elephant)
五 is five
毋 do not, must not, be not, mother radical (I knew it was mother, but not radical)
    And that's it, not too many.
But if such method makes sense not only to learn them, but also to find the primal forms in hieroglyphic canon, I'd rather watch at divination bones, those should be simpe, I remember I saw Eye there, Where's eye? It is 5 strokes. Let's move on.
目 is eye
甘 sweet, coax, pamper, be content, sugary
田 rice field
用 utilize, business, service, use, employ
白 white
百 hundred
皿 dish, a helping, plate
血 blood
立 stand up, rise, set up, erect
位 rank, grade, throne, crown, about, some
⺅stands for a man (it's weird that dictionaries don't tell it, probably those who write those dictionaries want to earn on language lessons)
世 generation, world, society, public. I knew it as world, and it's [se] and looks like c so I say let it be one of those letters.
冊 tome, counter for books, volume
母 now this is the mother I was looking for in 毋

耳 ear (this hieroglyph is so simple, that I must go on. Why do I torture you with this? I write this book for myself, it's my draft now. I should have split this text long ago, but it's too late to do it, let you see how I work, so you will see discoveries as they happen and you will calculate probability of these thoughts being apophenia - I bet on it's being valuable science, you should read further if you agree. You may write to me if you don't. 

But I realize 耳's almost indistinguishable from 目
So let's search those hierogliphy, which may relate to european letters to see if we can find anything out of this experiment:

一 is I because it sounds like [i] and as numerals it's also 90 degrees to I

人 looks like greek (and russian) Λ and it is transliterated as Ren, it sounds as Yen, and when I studied chinese the guy who taught me told that it's not [y] but [j] which could be difference of mandarin & cantonese. I still don't know it. I only know tea is te in cantonese of HongKong thus tea in english, and cha in mandarin of Beijing thus чай in russian. But google pronounces 茶 as cha, thus it's mandarin
But 人 still feels as it is as basic as A. out of my mind it's li or ri, and stands for man, but is it so.. or Λ?
Yet speaking of [y] it looks like upside down Y. (you should only fancy this part if you know chinese)
                                                                                 (because I don't know chinese, don't learn it here)
力 is K not only because it looks like one, especially in the form of か
but also because sounds か as Ka. ᚳ also can be related. or not, but if it helps you to link these pieces in one lace, it is.

耳 (ear) in chinese is literally Ěr (though I'm not sure google reads chinese well, I linked it)

The End of the secret level.
