Yes the Game  (Engine)  is written in Purebasic (started with 5.72,5.73,6.00 (alpha),6.00 Beta 1, is the actual version, Im using.

At start used  6.00 with the inbuild Purebasic  (ASM) Compiler, because I got some ASM errors, but now  i have found out whre the problem was (some code provided from the community, written in ASM), I removed this code and now i can use the C backend with no problems so far.

Maybe, because I use  "pure" Purebasic commands and Windows API calls, it works fine.

The source now  is about 24000 lines , it does not compile as fast as the ASM compiler. (It takes  about   2...3 sec)

There may be a small performance upgrade, but I think  I will have to optimize some   procedures .

The  origin game (Engine) "Thorins Quest", was recompiled with the new  C backend and works fine.
