I loved Amiga Basic. My first taste of programming without line numbers.
There's Cursor[0], a compiler with an editor from 1994, unfortunately proprietary and not further developed. Maybe someone could get a hold of the author to try and get them to open the source code for preservation and potential further development.
There's also aqb[1], a reboot, MIT license.
And a very nice alternative in AmigaOS, Blitzbasic, got its source code opened and forked, with renewed development for AmigaOS as AmiBlitz3[2], as well as ports to other platforms.

As for C wannabe, BASIC got famous before C had any meaningful meaning outside Bell Labs.
Dartmouth BASIC and timesharing were remarkable achievements: a simplified version of Fortran that could be learned in an afternoon but could be used for a wide variety of programs, including games; a fast, interactive compiler; and efficient resource usage and multiplexing that enabled a single machine to be shared by dozens (?) of interactive users. BASIC was also simple enough that it could be implemented compactly and efficiently on 8-bit microcomputers, while retaining its ease of learning for beginners and non-experts. And you could still write/run games with it.
So there is nothing like wanting to be like C, when its mainstream adoption predates C.
Actually I am quite thankful to have learnt systems programming on 8 and 16 bit systems, with BASIC and Pascal variations, macro Assemblers, exactly long before C's mainstream adoption, because I am not tainted with the idea before C there was nothing else, as it eventually became a common myth.
On Pascal, good for DOS, and maybe the Classic Mac, but even under Unix there were really good underused platforms, like TCL/Tk +SQLite. More crude than VB, for sure; but, seriously, most of the time a quick tool in that language would cover the 90% of the needs of any corporation.
Of course even though the 8-bit was only running at ~1Mhz compared to the Amiga's ~7Mhz, the 8-bit's ROM BASIC was written in hand-coded assembler (and by some really good programmers, including BillG himself (in the case of the Radio Shack Color Computer I used)). I think AmigaBASIC must have been written in C and designed with portability in mind.
But it turned out it was basically unusable on a TV because of the narrow cursor and difficult to read font. But AMOS was great, and we built a simple one-room adventure game prototype on it.
