The only point of articulation is bilabial in the consonants.

voiceless plosive: p
voiced plosive: b
voiceless fricative: ph
voiced fricative: bh
voiceless affricate: pph
voiced affricate: bbh
voiceless trill: pp
voiced trill: bb
voiced nasal: m
"forced" nasal: mh

I'm not entirely sure how to classify this "forced" nasal, but it sounds exactly like "Mmhmm", without the initial M sound. This sound can only appear in the initial syllable position. All other sounds can appear anywhere. Plosives are always released in coda position. 

There is also an unintentional glottal stop that evolved between the vowels e and a, in either order.

Unrounded open back: a
Round close back: u
Unrounded close central: i
middle central (schwa): e

A bilabial lateral? That would be a sight!

There are few fusional morphemes existing. Four tenses suffixed on a verb, a plural suffix, an antonymizer suffix (I'm sure there's a word for this, but I really can't remember) like the mal- in Esperanto, and a concretizer suffix (again, can't remember) like the -ajx- in Esperanto.

All cases, except the accusative, are expressed through prepositions, including the genitive (even for pronouns).

There is only one form of any noun, the plural doesn't count. The only singular third person pronoun is meant as "he". In this language, an adjective must be applied to give the sense of the feminine gender, otherwise, most nouns take the sense of either masculine or neuter.

Single words for the concepts of number end at 5. After that, a string of words can express numerals up to 50, but it becomes long and discouraged. 
Examples: 
miph eb pu (five and one), bbhe amipu (two threes), etc. = six
ami eb ami bbhepu eb mi pu (three and three twos and not one)= eleven
miph eb miph miphupu (five and five fives)= fifty

There is no need for the speakers of this language to ever need to write, their main concern is survival, living in a woods filled with dangerous animals, etc. The only place where words are kept is in a single notebook where the language's vocabulary and grammar were first recorded. There are nearly no native born speakers of this language, being that the banished groups consist mostly of men. Nevertheless, there is always a surplus of banished men to keep the language alive.

When I first thought of this language, I wanted to prove to myself that a language can have a consonant inventory made by a single articulatory point. So in that sense, this language began as an engelang. But when I started to think of a situation when this criterion could be filled, and because I chose bilabial, a story emerged. Now it's a proud artlang.
