It started off as a side project by myself, I'm a student so I work on it every now and then, but I'm 17 so I have bigger things to prioritise like my education. The large commit count is due to a certain someone cough Vedant cough making several accounts and doubling the commit history when he re-authors his commits.
The fact that it's a year old is because the language has changed loads in the past, since I considered it a side-project that I would just play around with. However, after I stuck to something, it gained a bit more popularity and people started to help me out with it. Now we have ported to Go, with a decent sized team working on it (when we can).
I recommend increasing the number of tests significantly, this is really important. A compiler is one of the easiest bits of software to test, so mastering good practice here will help you in the future.
